  text: From: The Exploratorium: http://www.exploratorium.edu/climate/glossary/ice-core.html
definition: An ice core is a section of ice drilled from a glacier or ice sheet. Icedeposits contain samples of the atmosphere at the time the ice formed; theyalso record seasonal fluctuations of temperature and dust. That's why ice coresare extremely valuable sources of paleoclimate data on the Earth's climatein the distant past. Researchers drill sections of ice cores hundreds of meterslong and then match sections at different depths with particular eras in theEarth's past. These sections can then be analyzed for clues about atmosphericgases and temperatures from hundreds of thousands of years ago.

definition: Solar energetic particles are high energy particles occasionally emitted fromactive areas on the Sun, associated with solar flares and coronal massejections. The Earth¿s magnetic field keeps them out of regions close to Earth(except for the polar caps) but they can pose a hazard to space travelers farfrom Earth. Solar energetic particles are somtimes referred to as solar cosmicrays.

NOCTILUCENT CLOUDS
type: Concept

change note: Date=2013-03-20 User Id=mpmorahan Entity=Definition Operation=INSERT System Note=insert Definition New Value=id: null text: The summer polar mesopause is the coldest region of the Earth's atmosphere, reaching temperatures as low as -140°C. It is sufficiently cold for noctilucent ('night shining') clouds to form in summer, at altitudes around 83 km. Noctilucent clouds can only be seen when the sun is shining on them (at ~83 km) and not on the lower atmosphere, i.e. when the sun is between 6 and 16 degrees below the horizon. They are a summer, polar phenomena but because of the restrictive viewing conditions they are most commonly observed at latitudes between 55 and 65 degrees. Noctilucent clouds were first reported in 1885 when they were independently observed in Germany and Russia. This was two years after the volcanic explosion of Krakatoa in the Straits of Java. One hypothesis is that the initial observation of noctilucent clouds was related to an increase in the number of observers of the twilight skies attracted by the spectacular displays resulting from the globally distributed volcanic debris of Krakatoa. Alternatively, water vapour injected into the upper atmosphere by the volcano ultimately reached the cold, dry upper mesophere. Subsequent observations have proved that noctilucent clouds are not solely related to volcanic activity, and their volcanic association is now scientifically contentious. It has been alternatively claimed that the appearance of noctilucent clouds is the earliest evidence of anthropogenic climate change.

definition: The summer polar mesopause is the coldest region of the Earth's atmosphere, reaching temperatures as low as -140°C. It is sufficiently cold for noctilucent ('night shining') clouds to form in summer, at altitudes around 83 km. Noctilucent clouds can only be seen when the sun is shining on them (at ~83 km) and not on the lower atmosphere, i.e. when the sun is between 6 and 16 degrees below the horizon.They are a summer, polar phenomena but because of the restrictive viewing conditions they are most commonly observed at latitudes between 55 and 65 degrees. Noctilucent clouds were first reported in 1885 when they were independently observed in Germany and Russia. This was two years after the volcanic explosion of Krakatoa in the Straits of Java.One hypothesis is that the initial observation of noctilucent clouds was related to an increase in the number of observers of the twilight skies attracted by the spectacular displays resulting from the globally distributed volcanic debris of Krakatoa. Alternatively, water vapour injected into the upper atmosphere by the volcano ultimately reached the cold, dry upper mesophere.Subsequent observations have proved that noctilucent clouds are not solely related to volcanic activity, and their volcanic association is now scientifically contentious. It has been alternatively claimed that the appearance of noctilucent clouds is the earliest evidence of anthropogenic climate change.Noctilucent cloud observations from north-west Europe over the last 30 years show an increasing trend in the number of nights on which the clouds are observed each summer season, superimposed on a decadal variability that appears to be solar-cycle related.Competing anthropogenic explanations for this increasing occurrence of noctilucent clouds focus on either excessive greenhouse cooling of the middle atmosphere or increased water vapour linked to increased methane release associated principally with intensive farming activities.They have been observed thousa…

definition: Geodesy is the science of the Earth’s shape, gravity, and rotation, including their evolution in time. Several techniques are used to observe the geodetic properties of the Earth, including Global Navigation Satellite Systems (GNSS), Satellite Laser Ranging (SLR), Very Long Baseline Interferometry (VLBI), and the Doppler Orbitography and Radio-Positioning by Integrated Satellite (DORIS) system. These space-geodetic observations also provide the basis for the reference frame that is needed in order to assign coordinates to points and objects and thereby determine how those points and objects move over time.

definition: Subsetting/Supersetting services are defined as Data Handling Services that, in the case of subsetting, create a smaller set of Earth science data from a larger set. In the case of supersetting the service creates an aggregate dataset from the contents of several data sets. In no instance of supersetting or subsetting is the data transformed (see transformation) (e.g., averaging), only transferred from one data set to another. EXAMPLES: Global cloud-free composite image (supersetting). Selecting one station's data from a data set containing 40 stations (subsetting).

AURORA FORECASTS
type: Concept
reference:
  text: Adapted from Space Weather Center, 'http://www.spaceweathercenter.org/glossary/001/01.html'
definition: Forecasts that help scientists predict the occurance of aurora. An aurora is the bright emission of atoms and molecules in Earth's polar upper atmosphere that appears as permanent, ring shaped belts called the auroral oval around thenorth and south magnetic poles. Aurora are associated with a global electrical discharge process triggered by solar wind disturbances. The emissions are caused by energetic particles from Earth's magnetotail region impinging on the upper atmosphere. Aurora occur about 70 miles above Earth's surface. Contrary to popular belief, they do not produce any sounds.

  text: Adapted from: Gould, J. and W.Keaton. 1996. Biological Science. W.W. Norton and Company. New York, New York.
definition: Mosses and Liverworts belong to the Phylum Bryophyta, Class Musciand Hepaticae, respectively. Bryophytes are relatively small plants thatgrow in moist places on land -- on damp rocks and logs, on the forestfloor, in swamps or marshes, or beside streams and pools. In a moss, thesporophyte stage of the life cycle is a relatively simple structureconsisting of three parts: a foot embedded in the 'leafy' greengametophyte, a stalk, and a distal capsule, or sporangium. The gametophyteplants of some liverworts resemble mosses except that the 'leaves' arescaly in appearance, and the 'stem' is prostrate. Other liverworts growas flat green structures lying on the substratum.

Depending on the temperature of evaporation and how far the water has had to travel before it fell as snow, the ratio of 18O to 16O will vary. This ratio, known as d18O, can be measured very accurately using a mass spectrometer. Over short time scales the change in temperature from summer to winter produces a very clear oscillation in the 18O/16O ratio. This oscillation is used to determine the age of the core at different depths, simply by counting the oscillations. Over longer time periods, this ratio indicates the average temperature of the regions between the evaporation site and the coring site. Investigators in Greenland and Antarctica are also analyzing for the ratio of 1H/2H (Hydrogen to deuterium) which will allow even finer detail about source temperature and condensation history to be obtained. language code: en

definition: The isotopic record found in ice cores reveal direct information about the past climate. d18O (delta oxygen-18), 16O and 18O are isotopes of oxygen with slight differences in atomic weight. Depending on the temperature of evaporation and how far the water has had to travel before it fell as snow, the ratio of 18O to 16O will vary. This ratio, known as d18O, can be measured very accurately using a mass spectrometer. Over short time scales the change in temperature from summer to winter produces a very clear oscillation in the 18O/16O ratio. This oscillation is used to determine the age of the core at different depths, simply by counting the oscillations. Over longer time periods, this ratio indicates the average temperature of the regions between the evaporation site and the coring site. Investigators in Greenland and Antarctica are also analyzing for the ratio of 1H/2H (Hydrogen to deuterium) which will allow even finer detail about source temperature and condensation history to be obtained.

ICE SHEETS
type: Concept
reference:
  text: American Meteorological Society Glossary of Meteorology. 'http://amsglossary.allenpress.com/glossary/'
definition: A continuous sheet of land ice that covers a very large area and moves outward in many directions. This type of ice mass is so thick as to mask the land surface contours, in contrast to the smaller and thinner highland ice. The continental glacier of Greenland is sometimes called the Inland Ice. This term is often used to describe the great ice masses that characterized the ice ages.

Atmospheric CO2 has increased about 25 percent since the early 1800s, with an estimated increase of 10 percent since 1958 (burning fossil fuels is the leading cause of increased CO2, deforestation the second major cause). The increased amounts of CO2 in the atmosphere enhance the greenhouse effect, blocking heat from escaping into space and contributing to the warming of Earth's lower atmosphere. (Earth Observatory) The most direct method for measuring atmospheric carbon dioxide concentrations for periods before direct sampling is to measure bubbles of air (fluid or gas inclusions) trapped in the Antarctic or Greenland ice caps. The most widely accepted of such studies come from a variety of Antarctic cores and indicate that atmospheric CO2 levels were about 260¿280uL/L immediately before industrial emissions began and did not vary much from this level during the preceding 10,000 years. The longest ice core record comes from Vostok, Antarctica, where ice has been sampled to a depth of 3,600 meters, corresponding to an age of 420,000 years before the present.

  text: Adapted from the National Drought Mitigation Center and the United States Drought Monitor
definition: Drought severity is a relative term that broadly refers to how intense a drought is considered to be. Drought severity can be measured through any number of physical indicators, such as rainfall or streamflow, but it can also be assessed through impacts to other interdependent systems given that drought affects water supply,agriculture, wildfire, and more. Drought frequency, duration, and severity are often used together as a means to describe and evaluate drought conditions in a given area (i.e., how often an area is affected bydrought, how long is it affected, and how severely it is affected).

  text: Adapted from Rice University Glacier Index, 'http://www.glacier.rice.edu/'
definition: A glacier is an accumulation of ice, air, water, and rock debris or sediment. It is a large enough quantity of ice to flow with gravity due to its own mass. The ice can be as large as a continent, such as the icesheet covering Antarctica; or, it can fill a small valley between two mountains, such as a valley glacier. 'Glacial landforms/processes' refers to the erosional or depositional processes of glaciers and the landforms (e.g., drumlins, cirques, fjords) that result.

definition: Drought duration refers to the length of time over which drought conditions persist. Drought frequency, duration, and severity are often used together as a means to describe and evaluate drought conditions in a given area (i.e., how often an area is affected by drought, how long is it affected, and how severely it is affected).

LANDSLIDES
type: Concept

  text: Jackson, Julia A. (1997) Glossary of Geology, 4th Edition. Alexandria, VA: American Geological Institute, 769 p. See 'http://www-socal.wr.usgs.gov/north/landslide.html' as an example. For contributing factors to landslides,see 'http://landslides.usgs.gov/html_files/nlic/page5.html'.
definition: A general term covering a wide variety of mass-movement landforms and processesinvolving the downslope transport, under gravitational influence, of soil and rock material en masse. Usually the displaced material move over a relatively confined zone or surface of shear. The wide range of sites and structures, andof material properties affecting resistance to shear, result in a great range of landslide morephology, rates, patterns of movement, and scale. Landsliding is usually preceded, accompanied, and followed by imperceptible creep along thesurface of sliding and/or within the slide mass. Terminology designating landslide types generally refers to the landform as well as the process responsible for it, e.g. rockfall, translational slide, block glide, avalanche,mudflow, liquefaction slide and slump. A Landslide Advisory may be included in other types of advisories such as ones for earthquakes, volcanic activity, and floods. Landslide advisories may alsotake the form of landslide susceptibility and probability maps.

  text: Burn, David M. Animal World. 1980. Octopus Books Ltd. London.
definition: Amphibians are craniates with a permeable skin across which respiration can take place. Their life cycle includes a shell-less egg which gives rise to a distinct larval form. The amphibians are free living in fresh water and on land (some are arboreal) but all are dependent on water or damp conditions.

definition: Halons are a group of brominated organic compounds used as fire retardants. Thetransport of these compounds to the stratosphere, followed by their photolysisto release Br (Bromine) atoms, gives this group a very high ozone depletionpotential. The production of these compounds is now banned according to theMontreal Protocol. Halogens are made up of the elements fluorine (F), chlorine (Cl), bromine (Br),iodine (I), and astatine (At). The first four members are present in traceamounts in the atmosphere as a result of both natural and anthropogenicactivity.

definition: Monitoring water storage and its variations is impor-tant to understanding local hydrological processesand the global water cycle, which sustains all life onEarth. The development of satellite remote-sensingtechniques has benefited the retrieval of terrestrialwater storage and its variations, which has emerged asa new discipline. Focusing on terrestrial water storage,this chapter describes three major retrievalapproaches: the water-balance-based approach, thesurface-parameter-based approach, and the GravityRecovery and Climate Experiment (GRACE)-basedapproach. Accurate estimates of terrestrial waterstorage and its variations are still being developed.

definition: Hydrogen cyanide (HCN) was discovered by the Swedish chemist Carl Wilhelm Scheele in 1782, who prepared it from the pigment Prussian blue (hence its other name of prussic acid). There are many naturally occurring substances yielding cyanide in certain seeds, such as the pit of the wild cherry. It usually occurs in combination with plant sugars. The tuberous edible plant of the spurge family called cassava (also known as manioc, mandioc, or yuca) was used by primitive peoples to produce HCN for poison darts and arrows. HCN is produced by other plants, bacteria and fungi. Emissions from CN radicals are occasionally observed from lightning disturbed air. Hydrogen cyanide is produced by biomass burning since nitrogen in plant material is mostly present as amino acids and upon combustionthis nitrogen is emitted as a variety of compounds including NH3, NO, NO2, N2O,organic nitriles and nitrates. It is interesting to note that the atmospheric measurements of HCN reported by Zander et al. (1988) gave a mixing ratio for HCN in the Southern Hemisphere which was approximately 5% higher than that for the Northern Hemisphere. This may be due to biomass burning. There are many anthropogenic sources of compounds containing CN which can be released into the atmosphere. Cyanides are used in a variety of chemical processes including fumigation, case hardening of iron and steel, electroplating and in the concentration of ores. Hydrogen cyanide is used to prepare polyacrylonitrile fibres (known by the generic name of acrylic) synthetic rubber, plastics, and in gas masers to produce a wavelength of 3.34 mm. Hydrogen cyanide is a combustion product which is a human hazard during domestic and industrial fires and from tobacco smoking. Some catalytic converters in bad repair can produce large amounts of Hydrogen cyanide. Hydrogen cyanide is produced in large quantities for laboratory and commercial use by three principle methods: Treatment of sodium cyanide with sulphuric acid, catalytic o…

reference:
  text: https://www.ncbi.nlm.nih.gov/pubmed/26769304
definition: Long-chain polyunsaturated fatty acids (LC-PUFA) are major components of complex lipid molecules and are also involved in numerous critical biological processes. Studies conducted mainly in vertebrates have demonstrated that LC-PUFA can be biosynthesized through the concerted action of two sets of enzymes, namely fatty acyl desaturases (Fads) and elongation of very long-chain fatty acid (Elovl) proteins. While LC-PUFA research is a thriving field, mainly focused on human health, an integrated view regarding the evolution of LC-PUFA biosynthetic genetic machinery in chordates is yet to be produced. Particularly important is to understand whether lineage specific life history trajectories, as well as major biological transitions, or particular genomic processes such as genome duplications have impacted the evolution of LC-PUFA biosynthetic pathways. Here we review the gene repertoire of Fads and Elovl in chordate genomes and the diversity of substrate specificities acquired during evolution. We take advantage of the magnitude of genomic and functional data to show that combination duplication processes and functional plasticity have generated a wide diversity of physiological capacities in extant lineages. A clear evolutionary framework is provided, which will be instrumental for the full clarification of functional capacities between the various vertebrate groups

definition: An interaction in which a perturbation in one climate quantity causes achange in a second and the change in the second quantity ultimatelyleads to an additional change in the first. A negative feedback is one inwhich the initial perturbation is weakened by the changes it causes; apositive feedback is one in which the initial perturbation is enhanced.The initial perturbation can either be externally forced or arise as part ofinternal variability.

Variances in climate forcing are determined by physical influences on the atmosphere such as orbital and axial changes as well as the amount of greenhouse gas in our atmosphere.

TROPHIC DYNAMICS
type: Concept

  text: Nebel, Bernard J. and Richard T. Wright. Environmental Science: the Way the World Works.-6th ed. 1998. Prentice Hall, Inc. Upper Saddle River, New Jersey.
definition: Trophic dynamics are major interactions among organisms which involvefeeding relationships. The feeding levels are called trophic levelswhere all producers belong to the first trophic level; all primaryconsumers (in other words, all herbivores), whether feeding on living ordead producers, belong to the second trophic level; organisms feeding onthese herbivores belong to the third level, and so on.

A vulnerability index for the natural environment, the basis of all human welfare, has been developed by the South Pacific Applied Geoscience Commission (SOPAC), the United Nations Environment Programme (UNEP) and their partners. The index was developed through consultation and collaboration with countries, institutions and experts across the globe. This index is designed to be used with economic and social vulnerability indices to provide insights into the processes that can negatively influence the sustainable development of countries. The reason for using indices for this purpose is to provide a rapid and standardised method for characterising vulnerability in an overall sense, and identifying issues that may need to be addressed within each of the three pillars of sustainability, namely environmental, economic and social aspects of a country’s development. Development is often achieved through trade-offs between these pillars. Therefore, in order to promote sustainability, it has become increasingly important to be able to measure how vulnerable each aspect is to damage and to identify ways of building resilience. With this information to hand, the outcome for countries could be optimised for their unique situations and development goals. language code: en

definition: Terrestrial - related to the Earth, A hydrosphere is the total amount of water on a planet. The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice.On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground as groundwater, in wells and aquifers. Water vapor is most visible as clouds and fog.The frozen part of Earth's hydrosphere is made of ice: glaciers, ice caps and icebergs. The frozen part of the hydrosphere has its own name, the cryosphere. Water moves through the hydrosphere in a cycle. Water collects in clouds, then falls to Earth in the form of rain or snow. This water collects in rivers, lakes and oceans. Then it evaporates into the atmosphere to start the cycle all over again. This is called the water cycle.

  text: USDA
definition: Silviculture is the art and science of controlling the establishment, growth, composition, health, and quality of forests and woodlands to meet the diverse needs and values of landowners and society such as wildlife habitat, timber, water resources, restoration, and recreation on a sustainable basis. This is accomplished by applying different types of silvicultural treatments such as thinning, harvesting, planting, pruning, prescribed burning and site preparation. Intermediate treatments (thinning) are designed to enhance growth, quality, vigor, and composition of the stand after establishment or regeneration and prior to final harvest. Regeneration treatments (harvesting) are applied to mature stands in order to establish a new age class of trees. Regeneration methods are grouped into four categories: coppice, even-aged, two-aged, and uneven-aged.All vegetation activities, including prescribed fire, wildlife habitat improvement, timber harvesting and cutting trees in campgrounds for human safety must have a silvicultural prescription. A silvicultural prescription is a document which has a planned series of treatments designed to change current stand structure and composition of a stand to one that meets management goals. The prescription normally considers ecological, economic, and societal objectives and constraints. In the Forest Service, silvicultural prescriptions are prepared or reviewed by a certified silviculturist prior to implementing the project or treatment.

definition: Fatty acid desaturases are enzymes that introduce double bonds into fatty acyl chains. They are present in all groups of organisms, i.e., bacteria, fungi, plants and animals, and play a key role in the maintenance of the proper structure and functioning of biological membranes. The desaturases are characterized by the presence of three conserved histidine tracks which are presumed to compose the Fe-binding active centers of the enzymes. Recent findings on the structure and expression of different types of fatty acid desaturase in cyanobacteria, plants and animals are reviewed in this article. Roles of individual desaturases in temperature acclimation and principles of regulation of the desaturase genes are discussed.

definition: Black carbon is one kind of aerosols. In climatology, black carbon is a climate forcing agent contributing to global warming. Chemically, black carbon (BC) is a component of fine particulate matter (PM ≤ 2.5 µm in aerodynamic diameter). Black carbon consists of pure carbon in several linked forms. It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is one of the main types of particle in both anthropogenic and naturally occurring soot. Black carbon causes human morbidity and premature mortality. Because of these human health impacts, many countries have worked to reduce their emissions, making it an easy pollutant to abate in anthropogenic sources.

  text: Foukal, P., ed. 1987. Solar Radiative Output Variation: Proceedings of a Workshop held Nov. 9-11, 1987 at NCAR, Boulder, CO. Cambridge Research and Instrumentation, Inc.
definition: Radiation with wavelengths roughly between 200 and 400 nanometers.These wavelengths are shorter than those which characterize visiblelight. Observations from satellites in the UV and extreme UV (EUV)wavelengths have demonstrated the sun's UV variability over short timescales of days and weeks. UV variability is linked to solar magneticactivity phenomena such as flares and plages. Studies of the UV and EUVirradiance variability may have indicated influences on the Earth'sclimate dynamics.

reference:
  text: https://en.wikipedia.org/wiki/Sea_salt_aerosol McComiskey, A.(Editor), Andrews, E., et al., Aerosols and Radiation - NOAA Earth System Research Laboratory IPCC Third Assessment Report: Climate Change 2001
definition: Sea salt aerosol, which originally comes from sea spray, is one of the most widely distributed natural aerosols. Sea salt aerosols are characterized as non-light-absorbing, highly hygroscopic, and having coarse particle size. Some sea salt dominated aerosols could have a single scattering albedo as large as ~0.97. Due to the hygroscopy, a sea salt particle can serve as a very efficient cloud condensation nuclei (CCN), altering cloud reflectivity, lifetime, and precipitation process. According to the IPCC report, the total sea salt flux from ocean to atmosphere is ~3300 Tg/yr

SOLAR X-RAY EMISSIONS
type: Concept
reference:
  text: On-Line Glossary of Solar-Terrestrial Terms from the NOAA Space Environment Laboratory. 'http://www.ngdc.noaa.gov/stp/GLOSSARY/glossary.html'
definition: Solar X-Ray emissions can consist of X-Ray background flux or X-Ray bursts. Adaily average background X-ray flux is in the 1 to 8 angstrom range. It is amidday minimum designed to reduce the effects of flares. X-Ray burstsare atemporary enhancement of the X-ray emission of the sun. The time-intensityprofile of soft X-ray bursts is similar to that of the H-Alpha profile of anassociated flare. Bursts last from minutes to several hours.

SOLAR VELOCITY FIELDS
type: Concept
reference:
  text: http://astrowww.phys.uvic.ca/grads/simard/phd/root/node34.html
definition: Solar velocity fields are also known as differential rotation. The sun rotatesslightly more rapidly at the equator than at the poles. Gases at the equatormake about 10 rotations, whiles gases at midlatitudes rotates 9 times and gasesat the poles rotates about 7 times. This produces a shear in the gas motionsand a pronounced E-W orientation of the magnetic field.

Degree days are the difference between the daily temperature mean, (high temperature plus low temperature divided by two) and 65°F. If the temperature mean is above 65°F, we subtract 65 from the mean and the result is Cooling Degree Days. If the temperature mean is below 65°F, we subtract the mean from 65 and the result is Heating Degree Days. -------------------------------------------------------------------------- Example 1: The high temperature for a particular day was 90°F and the low temperature was 66°F. The temperature mean for that day was: ( 90°F + 66°F ) / 2 = 78°F Because the result is above 65°F: 78°F - 65°F = 13 Cooling Degree Days Example 2: The high temperature for a particular day was 33°F and the low temperature was 25°F. The temperature mean for that day was: ( 33°F + 25°F ) / 2 = 29°F Because the result is below 65°F: 65°F - 29°F = 36 Heating Degree Days.

definition: The sum of exchangeable bases plus total soil acidity at a specific pH value usually 7.0 or 8.0. When acidity is expressed as salt extractable acidity, the cation exchange capacity (CEC) is called the effective cation exchange capacity(ECEC) because this is considered to be the CEC of the exchanger at the native pH value. It is usually expressed in centimoles of charge per kilogram of exchanger.

A layer of soil or bedrock at a variable depth beneath the surface of the earth in which the temperature has been below freezing continuously from a few to several thousands of years. Permafrost exists where the summer heating fails to descend to the base of the layer of frozen ground. A continuous stratum of permafrost is found where the annual mean temperature is below about 5C (23F). 2. As limited in application by P. F.

definition: The age of the sea ice is usually a distinction between first-yearand multiyear ice. Multiyear sea ice is usually thicker, has more ridges,and can be more of a hinderance to ship travel than first-year ice.Microwave remote sensing studies have shown that first-year sea ice has ahigher emissivity at the 1.55 cm wavelength than multiyear ice, thusmaking it possible to distinguish between different ice ages fromsatellites. Ice age can also be qualitatively determined using visible,infrared and radar wavelengths from satellites.

type: Concept
reference:
  text: http://www-istp.gsfc.nasa.gov/Education/gloss.html
definition: A magnetic storm is a large-scale disturbance of the magnetosphere, ofteninitiated by the arrival of an interplanetary shock originating at the Sun. Amagnetic storm is marked by the injection of an appreciable number of ions fromthe magnetotail into the ring current, a process accompanied by increasedauroral displays. The strengthened ring current causes a world-wide drop in theequatorial magnetic field, taking perhaps 12 hours to reach its greatestintensity, followed by a more gradual recovery.

ELECTRIC FIELDS/ELECTRIC CURRENTS
type: Concept
reference:
  text: http://www-istp.gsfc.nasa.gov/Education/gloss.html
definition: An electric field is the region in which electric forces can be observed, e.g. near a charged particle. As a field, it may also be viewed as a region of space modified by the presence of electric charges. An electric current is a continuous flow of electrons and/or ions, through a material which conducts electricity. A current usually flows in a closed circuit, without beginning or end. In daily life, currents are generally driven through wires by voltages produced by batteries or generators. In space plasmas, currents are produced by the movement of charged paricles in the presence of a magnetic field.

OXYGEN ISOTOPES
type: Concept
reference:
  text: Bradley, R.S. 1999. Paleoclimatology: Reconstructing Climates of the Quaternary, 2nd edition. Harcourt Academic Press (especially Chapter 6.3).
definition: Isotopes of oxygen (O-18, O-16, O-13) are found in calcium carbonate in seawater. The production of O18 is highly dependent on temperature. The oxygenisotope record in marine sediments varies locally with temperature and globallywith variations in continental ice volume. Oxygen isotope analyses have beencarried out on deep sea cores from areas of calcareous sedimentation throughoutthe world and similar variations in O18 are recorded everywhere. The O18 signalis that of ice volume changes on the continents and concomitant changes in theisotopic content of the oceans.

WPS can describe any calculation (i.e. process) including all of its inputs and outputs, and trigger its execution as a Web Service. WPS supports simultaneous exposure of processes via HTTP GET, HTTP POST, and SOAP, thus allowing the client to choose the most appropriate interface mechanism. The specific processes served up by a WPS implementation are defined by the owner of that implementation. Although WPS was designed to work with spatially referenced data, it can be used with any kind of data.

  text: From: http://en.wikipedia.org/wiki/Glaciation
definition: A glaciation (a created composite term meaning Glacial Period, referring to thePeriod or Era of, as well as the process of High Glacial Activity), oftencalled an ice age, is a geological phenomenon in which massive ice sheets formin the Arctic and Antarctic and advance toward the equator. Conversely, theterm interglacial or Interglacial Period, such as the current era, is used todenote the absence of large-scale glaciation on a global scale ¿ i.e., anon-Ice Age. Interglacials are, in general, shorter than glacial epochs.

Divergence is a distribution of wind movement that results in a net outflow of air from an area. New Value=Pressure fluctuations at the Earth's surface are produced by movements of air which produce changes in the mass of air in a vertical column above the ground. A net gain in mass produces an increase in pressure leading to a high pressure system. A net loss of mass gives rise to a low. When there is a horizontal flow of air into a region (convergence) a vertical upward movement of air occurs otherwise there would be a continual increase in density of the air. Divergence occurs when there is a net horizontal outward flow of air from a region. This leads to a vertical downward movement of air.

change note: Date=2021-02-26 User Id=tstevens Entity=Definition Operation=UPDATE Field=text System Note=update Definition Old Value=Ozone (O3) is a molecule that consists of three oxygen atoms bonded together. The ozone layer in the stratosphere absorbs UV radiation and creates a warm layer of air high in the stratosphere. Ozone that is present in the troposphere is mostly a result of anthropogenic pollution and therefore higher concentrations are found in urban areas. Ozone is involved with NOx in the photochemical production of many of the constituents of pollution environments (see nitrogen oxides and hydroxyl definitions) [Chemical and Engineering News; v72; 6-7; 1994.] [Aviation Week and Space Technology; v140; 20-21; 1994.] New Value=Atmospheric Ozone is one of the most important trace gases in our atmosphere that both benefits and harms life on Earth. High ground-level ozone amounts contribute to poor air quality, adversely affecting human health, agricultural productivity, and forested ecosystems. Ozone absorbs infrared radiation, and is most potent as a greenhouse gas in the cold upper troposphere located 8–15 km above the surface. In the stratosphere, between approximately 15 and 50 km above the Earth’s surface, a layer rich in ozone serves as a “sunscreen” for the world by shielding the Earth’s surface from harmful ultraviolet radiation. This absorption of solar energy also affects atmospheric circulation patterns and thus influences weather around the globe. Moreover, throughout the atmosphere, ozone is the key ingredient that initiates chemical cleansing of the atmosphere of various pollutants, such as carbon monoxide and methane, among others, which could otherwise accumulate to harmful levels or exert a stronger influence on climate. Therefore, changes to ozone anywhere in the atmosphere can have major impacts on the Earth.

definition: The goal in constructing a precipitation-based measure of ENSO was to estimate the gradient of rainfall anomalies across the Pacific basin and ensure a good relationship with SST- and pressure-based indices. Areas were selected that represent the Maritime Continent (MC) (10° N – 10°S; 90° E – 150° E) and central to eastern Pacific (P) (10° N – 10° S; 160° E – 100° W). These regions capture the largest precipitation anomalies associated with the interannual variations of the Walker circulation and contain the largest correlations between GPCP and Nino 3.4 and SOI. Within P and MC the absolute magnitude of the largest correlation is over +0.6. Because of the spatially varying nature of rainfall, it was decided to use a moving block average which would capture the strongest zonal gradients within the equatorial Pacific. This procedure is unlike many fixed area average indices, and allows for a realistic meridional component of the precipitation gradient and migration of the ascending and descending branches of the Walker circulation.

definition: The relatively simple calculation of the Aerosol Index is based on wavelength dependent changes in Rayleigh scattering in the UV spectral range where ozone absorption is very small. UVAI can also be calculated in the presence of clouds so that daily, global coverage is possible. This is ideal for tracking the evolution of episodic aerosol plumes from dust outbreaks, volcanic ash, and biomass burning.

This phenomenon, termed temporary coalescence, can result in satellite droplets considerably smaller than either of the parent drops. This phenomenon is also called partial coalescence because the large drop may gain mass as a result of the higher internal pressure in the small drop. At still larger impact energy, drop breakup occurs for the smaller drop. About 20% of the high-energy collisions between large raindrops (d > 3 mm) and drizzle drops (d > 0.2 mm) result in the disintegration of both drops. Other factors that affect coalescence are electric charge and electric field, both of which promote coalescence, leading to earlier onset of coalescence during an interaction so that coalescence efficiencies are increased by suppression of rebound and temporary coalescence.

About 20% of the high-energy collisions between large raindrops (d > 3 mm) and drizzle drops (d > 0.2 mm) result in the disintegration of both drops. Other factors that affect coalescence are electric charge and electric field, both of which promote coalescence, leading to earlier onset of coalescence during an interaction so that coalescence efficiencies are increased by suppression of rebound and temporary coalescence. All of these processes are important in formation of precipitation in all liquid clouds both above and below 0°C.

definition: Radiolarians belong to the class Actinopoda, meaning 'ray feet' which refersto the numerous slender, reinforced pseudopods that radiate from the body.Like foramniferans, the radiolarians are well represented in the fossilrecord, for they have ornate, silica-hardened parts that resistdegradation. Radiolarian shells contribute to the formation of siliceousrocks such as chert.

definition: Hypoxia in aquatic systems refers to waters where thedissolved oxygen concentration is below 2 mg/L. Most organisms avoid, orbecome physiologically stressed, in waters with oxygen below thisconcentration. Also known as a dead zone, hypoxia can also kill marineorganisms which cannot escape the low-oxygen water, affecting commercialharvests and the health of impacted ecosystems.3. Rationale: Numerous researchers are studying hypoxia, the hypoxiczone, and its effect on fisheries. It is becoming a highly visible hottopic in the Gulf of Mexico and other regions as the onset of hypoxia islargely due to increased nutrient run off from agriculture practices in theMississippi River watershed. I think there needs to be a unifying keywordto link these datasets together for users to discover hypoxia related dataacross multiple organizations and programs.

change note: Date=2013-04-01 User Id=tbs1979 Entity=Definition Operation=INSERT System Note=insert Definition New Value=id: null text: A form of coastal or river erosion, when the bed load is eroded by itself. As rocks are transported downstream along a riverbed (by a mixture of rolling, sliding and saltating), the regular impacts between them cause them to be broken up into smaller fragments.

definition: A form of coastal or river erosion, when the bed load is eroded by itself. As rocks are transported downstream along a riverbed (by a mixture of rolling, sliding and saltating), the regular impacts between them cause them to be broken up into smaller fragments. This process also makes them rounder and smoother. Attrition can also occur in glaciated regions, where it is caused by the movement of ice with embedded boulders over surface sediments.

AVALANCHE FORECASTS
type: Concept
reference:
  text: Adapted from: 'http://en.wikipedia.org/wiki/Avalanche'
definition: An avalanche is caused when a build up of snow is released down a slope, and isone of the major dangers faced in the mountains in winter. In an avalanche,lots of material or mixtures of different types of material fall or sliderapidly under the force of gravity. Avalanches are often classified by whatthey are made of, for example snow, ice, rock or soil avalanches. A mixture ofthese would be called a debris avalanche. A large avalanche can run for miles, and can create massive destruction of the lower forest and anything else in its path. Avalanches occur when the load onthe upper snow layers exceeds bonding forces (bonding to layer beneath, supportfrom anchors such as rocks and trees, stress support from top or bottom ofslope). Critical load may be exceeded naturally by adding new snow or by rapid loading, by falling ice, cornices and similar means. The bonding forces within a snowpack are affected by temperatures (e.g., a lubricated melt layer, or afragile crystal layer) before, during and after snowfall. Avalanches are also triggered by humans - because of the additional weight, kicks during skiing (e.g. during jumps) or intentionally by explosives, slope-cuts and other means. An Avalanche Advisory reports on conditions favorable for an avalanche and willprovide locations in which an avalanche is more likely to occur.

New Value=A type of map characterized by large-scale detail and quantitative representation of relief, usually using contour lines in modern mapping, but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and man-made features. A topographic map is typically published as a map series, made up of two or more map sheets that combine to form the whole map. A contour line is a combination of two line segments that connect but do not intersect; these represent elevation on a topographic map.

definition: A type of map characterized by large-scale detail and quantitative representation of relief, usually using contour lines in modern mapping, but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and man-made features. A topographic map is typically published as a map series, made up of two or more map sheets that combine to form the whole map. A contour line is a combination of two line segments that connect but do not intersect; these represent elevation on a topographic map.

definition: An important baseline measurement in ice cores is electrical conductivity.Electrical conductivity measurements (ECM) of the core is a very rapid methodto indicate how acidic the core is without the chemical detail of the ionanalyses. The value of the measurement is that it can be done for the wholelength of the core in high resolution and provide an immediate picture of thecore and allow quick detection of interesting areas, such as a volcaniceruptions. Because it is a high resolution, continuous measurement it can beused, along with the other measurements, for time frequency analysis in orderto identify cycles in the climate signal.

type: Concept

change note: Date=2025-02-25 User Id=tstevens Entity=Definition Operation=UPDATE Field=text System Note=update Definition Old Value=The FAA Global Navigation Satellite System (GNSS) Program Office provides satellite (GPS) based positioning, navigation, and timing (PNT) services in the United States to enable performance-based (RNP/RNAV) operations for all phases of flight from en route, terminal, approach, and surface navigation. The GNSS Team, along with other FAA organizations and numerous governmental and non-governmental agencies, are all supporting a smooth transition to satellite navigation. New Value=A Global Navigation Satellite System (GNSS) is a space geodesy technique that provides autonomous geospatial positioning with global coverage. The U.S. Global Positioning System (GPS) is one type of GNSS. The current GPS constellation includes 24 satellites, each traveling in a 12-hour, circular orbit, 20,200 kilometers above the Earth. The satellites are positioned so that six are observable nearly 100 percent of the time from any point on Earth. The current GLObal NAvigation Satellite System (GLONASS) constellation includes 24 satellites, each traveling in a circular orbit 19,140 kilometers above the Earth. The satellites are positioned so that four are observable nearly 100 percent of the time from any point on Earth. GNSS receivers detect, decode, and process signals from the GNSS satellites. The satellites transmit the ranging codes on two radio-frequency carriers, allowing the locations of GNSS receivers to be determined with varying degrees of accuracy, depending on the receiver and post-processing of the data. A global network of several hundred permanent GNSS (GPS and GPS+GLONASS) receivers provide data. High-accuracy measurements of the change in receiver locations over time allow researchers to study the motions of tectonic plates, displacements associated with earthquakes, and Earth orientation.

definition: Indicator species are defined as species which can provide information on ecological changes and give early warning signals regarding ecosystem processesin site-specific conditions due to their sensitive reactions to them. They can also be called sentinel species, indicator organisms, biological indicators ('bioindicators'), biological markers, or environmental indicators. The latter three expressions do not necessarily refer to species but also to other environmental elements which can indicate environmental changes.

  text: Atmospheric and Air Chemistry Glossary from the Sam Houston State University. 'http://www.shsu.edu/~chemistry/Glossary/glos.html'
definition: CFCs are very stable chemical compounds, used in refrigerants, solvent, and (in the past in the U.S.) aerosols, which release chlorine (important) and fluorine (less important) into the upper atmosphere. In the stratosphere, CFCs are photolyzed (by incoming solar UV) to form carbon dioxide, CO2, hydrogen fluoride, HF, and ultimately (after multiple UV absorption events) chlorine radicals. These chlorine species are crucial in the destruction of the ozone layer over Antarctica and probably elsewhere (see chlorine). [Environmental Science and Technology; v 28; pages 1619-1622; 1994.]

METHYL BROMIDE
type: Concept
reference:
  text: [New York Times Aug. 16, 2003] [Baird, Colin. Environmental Chemistry. (1999) W.H. Freeman, New York.]
definition: CH3Br, this halocarbon is released, to a degree, naturally from the oceans, but is more commonly released from its anthropogenic use as a soil fumigant or pesticide. Methyl bromide is persistent enough to reach the stratosphere where it photochemically decomposes to yield atomic bromine (radical) and proceeds to destroy stratospheric ozone in the same manner as the atomic chlorine radical. On an atom-for-atom basis, stratospheric bromine is more efficient at destroying ozone than is chlorine because the HBr reservoir species is more photochemically active than HCl; however, there is much less of hydrogen bromide in the stratosphere. Recent data suggest that since 1998 atmospheric concentrations have dropped 13% due the CH3Br use limitations mandated by the Montreal Protocol

DROUGHT FORECAST
type: Concept

  text: http://drought.unl.edu/ http://www.droughtoutlook.com/
definition: Drought is a protracted period of deficient precipitation resulting in extensive damage to crops, resulting in loss of yield. Lack of rainfall for an extended period of time can bring farmers and major metropolitan areas to their knees. It does not take very long; a few rain-free weeks spreads panic and shrivels crops. A drought forecast would be issued forone of the following: Meteorological - a measure of departure of precipitation from normal. Due to climatic differences what is considered a drought in one location may not be a drought in another location. Agricultural - refers to a situation when the amount of moisture in the soil nolonger meets the needs of a particular crop and can also affect livestock and other dry-land agricultural operations. Hydrological - occurs when surface and subsurface water supplies are below normal. Socioeconomic - refers to the situation that occurs when physical water shortage begins to affect people.

definition: ClO2, a radical, undergoes photodecomposition in the stratosphere where the products of this reaction react with ozone. Since this is a photochemical reaction it only takes place while the sun is up. Experiments over Antarctica have shown a direct relation between polar ozone loss and the increase in halocarbon chemistry, which comes from anthropogenic sources. Scientist are currently looking at the molecular behavior of chlorine dioxide in the atmosphere in order to understand its role in depletion of ozone more thoroughly. [Simon, J. D. and Vaida, V.

definition: Measurement of water density taking water's compressibility intoaccount, provided no heat exchange of the water sample with itssurroundings. This is important because of the potential temperaturechange of water at varying levels of pressure. That is, under highpressure, water is warmer (less potentially dense) than that same sampleof water at low pressure (lower potential temperature and thus morepotentially dense).

CHLORINE NITRATE
type: Concept
reference:
  text: Atmospheric and Air Chemistry Glossary from the Sam Houston State University. 'http://www.shsu.edu/~chemistry/Glossary/glos.html'
definition: ClONO2 - This is a stratospheric reservoir species for chlorine and nitrogen, two of the catalysts in the breakdown of ozone. It reacts with HCl at low temperatures on the surfaces of polar stratospheric clouds (PSCs over Antarctica and possibly in the stratosphere over the Arctic). That normally slow reaction heterogeneously produces molecular chlorine and nitric acid. The former outgases from the PSC surface and is quickly photolyzed by 450 nm or shorter wavelength light to form chlorine radicals which rapidly catalyze the breakdown of ozone (see chlorine monoxide).

definition: The BEST index was designed to be simple to calculate and to provide a long time period ENSO index for research purposes. Nino 3.4 has traditionally been used as a measure of ENSO strength in the tropical Pacific. However, it's use alone neglects explicit atmospheric processes. By adding the SOI or Southern Oscillation Index (the pressure difference between Tahiti and Darwin), these processes are more directly included. In addition, older SST values are at least partially reconstructed and not explicitly measured. By including the SOI, which is better measured historically, the effect of biases in the SST data introduced by the reconstruction technique are reduced. A more detailed explanation how the index was created is available (http://www.esrl.noaa.gov/psd/people/cathy.smith/best/details.html).

The primary cause is the much greater annual variation of temperature over large land areas compared with neighboring ocean surfaces, causing an excess of pressure over the continents in winter and a deficit in summer, but other factors such as the relief features of the land have a considerable effect. The monsoons are strongest on the southern and eastern sides of Asia, the largest landmass, but monsoons also occur on the coasts of tropical regions wherever the planetary circulation is not strong enough to inhibit them. They have been described in Spain, northern Australia, Africa except the Mediterranean, Texas, and the western coasts of the United States and Chile. In India the term is popularly applied chiefly to the southwest monsoon and, by extension, to the rains which it brings.

Thecontinent margin is the zone separating the continents from the deep-seabottom, usually subdivided into the continental shelf, slope, and rise. They are two basic types of continental margins: passive, or Atlantic, marginsand active, or Pacific, margins. Passive margins have little seismic orvolcanic activity and form when continents are rifted apart, creating a newocean basin between them. Active margins are tectonically active and are mostoften associated with plate convergence and subduction.

Interpretation of this record reveals a diverse array of environmental signatures that include the documentation of anthropogenically derived pollutants, volcanic and biomass burning events, storminess over marine surfaces, continental aridity and biogenic source strength plus information related to the controls on both high- and low-frequency climate events of the last 110,000 years. Climate forcings investigated include changes in insolation of the order of the major orbital cycles that control the long-term behavior of atmospheric circulation patterns through changes in ice volume (sea level), events such as the Heinrich events (massive discharges of icebergs first identified in t he marine record) that are found to operate on a 6100-year cycle due largely to the lagged response of ice sheets to changes in insolation and consequent glacier dynamics, and rapid climate change events (massive reorganizations of atmospheric circulation) that are demonstrated to operate on 1450-year cycles. Changes in insolation and associated positive feedbacks related to ice sheets may assist in explaining favorable time periods and controls on the amplitude of massive rapid climate change events.

CARBONYL SULFIDE
type: Concept
reference:
  text: Atmospheric and Air Chemistry Glossary from the Sam Houston State University. 'http://www.shsu.edu/~chemistry/Glossary/glos.html'
definition: COS, a gas that is very stable and unreactive in the troposphere, but, it is thought, photolyzes to form carbon monoxide, CO, and sulfur, S, in the stratosphere. Through stratospheric chemical reactions, the sulfur atoms are converted to SO2 and H2SO4 which form sulfate aerosol, cloud condensation nuclei, but which eventually settles into the troposphere and reacts to form sulfuric acid, a component in acid rain. The major biospheric sources of COS are thought to be biological.

In the eastern United States, heat waves generally build up with southerly winds on the western flank of an anticyclone centered over the southeastern states, the air being warmed by passage over a land surface heated by the sun.

Strong sea surface temperature (SST) tripole events, which are defined by empirical orthogonal function of winter-mean interannual North Atlantic SST anomalies, are primarily induced by NAO in early winter and peak in January. In late winter, the persistent SST tripole exerts active feedback on atmosphere through diabatic heat and transient eddy forcing. The resulting atmospheric circulation anomalies exhibit an almost reversed NAO pattern in February, which forms a wavetrain originating above the Gulf Stream and propagating to the Middle East and weakens the former SST tripole.

reference:
  text: From NOAA/NWS: http://ww2.wrh.noaa.gov/climate_info/Arctic_N_Atlantic_Oscillation.htm' See also: 'http://horizon.atmos.colostate.edu/ao/
definition: The North Atlantic Oscillation (NAO) index is often defined as the difference of sea-level pressure between 2 stations situated close to the 'centres of action' over Iceland and the Azores. Stykkisholmur (Iceland) is invariably used as the northern station, whereas either; Ponta Delgada (Azores) Lisbon (Portugal) Gibraltar are used as the southern station. Strong positive phases of the NAO tend to be associated with above-normal temperatures in the eastern United States and across northern Europe and below-normal temperatures in Greenland and oftentimes across southern Europe and the Middle East. They are also associated with above-normal precipitation over northern Europe and Scandinavia and below-normal precipitation over southern and central Europe. Opposite patterns of temperature and precipitation anomalies are typically observed during strong negative phases of the NAO. During particularly prolonged periods dominated by one particular phase of the NAO, abnormal height and temperature patterns are also often seen extending well into central Russia and north-central Siberia.

change note: Date=2012-07-06 User Id=mpmorahan Entity=Definition Operation=INSERT System Note=insert Definition New Value=id: null text: The mode describes the meridional variabilty in the tropical Atlantic Ocean. Calculation Method: The AMM spatial pattern is defined via applying Maximum Covariance Analysis (MCA) to sea surface temperature (SST; left field) and the zonal and meridional components of the 10m wind field (right field) over the time period 1950-2005, from the NCEP/NCAR Reanalysis. To define the spatial pattern, data are defined over the region (21S-32N, 74W-15E), and spatially smoothed (three longitude by two latitude points).

definition: The mode describes the meridional variabilty in the tropical Atlantic Ocean.Calculation Method:The AMM spatial pattern is defined via applying Maximum Covariance Analysis (MCA) to sea surface temperature (SST; left field) and the zonal and meridional components of the 10m wind field (right field) over the time period 1950-2005, from the NCEP/NCAR Reanalysis. To define the spatial pattern, data are defined over the region (21S-32N, 74W-15E), and spatially smoothed (three longitude by two latitude points). The seasonal cycle is removed, data are detrended, a three-month running mean is applied to the data, and the linear fit to the Cold Tongue Index (a measure of ENSO variability) is subtracted from each spatial point. Spatial patterns are defined as the first left (SST) and right (winds) maps resulting from singular value decomposition of the covariance matrix between the two fields.

definition: The Niño 3 index is an average of the sea surface temperatures in the region 150 degrees West - 90 degrees West (longitude) and 5 degrees North to 5 degrees South (latitude). When the index is positive (red) then waters are warmer than normal and when the index is negative (blue) then waters are cooler than normal. El Niños occur when the water is much warmer than normal for a sustained period of time. For example, El Niños occured in 1982-83, 1986-87 and 1997-98

However, the causes of its occasional reversal between early and late winter remain unclear. This study proposes a mechanism for the mid-winter reversal of NAO from the perspective of local midlatitude air-sea interaction. Strong sea surface temperature (SST) tripole events, which are defined by empirical orthogonal function of winter-mean interannual North Atlantic SST anomalies, are primarily induced by NAO in early winter and peak in January. In late winter, the persistent SST tripole exerts active feedback on atmosphere through diabatic heat and transient eddy forcing. The resulting atmospheric circulation anomalies exhibit an almost reversed NAO pattern in February, which forms a wavetrain originating above the Gulf Stream and propagating to the Middle East and weakens the former SST tripole. Consequently, significant reversals of air temperature anomalies occur in Europe and the Caspian Sea area between February and December. language code: en

SEA SURFACE FOUNDATION TEMPERATURE

change note: Date=2019-08-28 User Id=sritz Entity=BroaderRelation Operation=INSERT User Note=Insert Concept System Note=add broader relation New Value=SEA SURFACE FOUNDATION TEMPERATURE [e4d58a7f-7eaa-4f75-996a-18238c698063,369095] - SEA SURFACE TEMPERATURE [bd24a9a9-7d52-4c29-b2a0-6cefd216ae78,83965]
definition: The sea surface foundation temperature is the water temperature that is not influenced by a thermally stratified layer of diurnal temperature variability (either by daytime warming or nocturnal cooling). The foundation temperature is named to indicate that it is the temperature from which the growth of the diurnal thermocline develops each day, noting that on some occasions with a deep mixed layer there is no clear foundation temperature in the surface layer. In general, sea surface foundation temperature will be similar to a night time minimum or pre-dawn value at depths of between approximately 1 and 5 meters. In the absence of any diurnal signal, the foundation temperature is considered equivalent to the quantity with standard name sea_surface_subskin_temperature. The sea surface foundation temperature defines a level in the upper water column that varies in depth, space, and time depending on the local balance between thermal stratification and turbulent energy and is expected to change slowly over the course of a day. If possible, a data variable with the standard name sea_surface_foundation_temperature should be used with a scalar vertical coordinate variable to specify the depth of the foundation level. Sea surface foundation temperature is measured at the base of the diurnal thermocline or as close to the water surface as possible in the absence of thermal stratification. Only in situ contact thermometry is able to measure the sea surface foundation temperature. Analysis procedures must be used to estimate sea surface foundation temperature value from radiometric satellite measurements of the quantities with standard names sea_surface_skin_temperature and sea_surface_subskin_temperature. Sea surface foundation temperature provides a connection with the historical concept of a 'bulk' sea surface temperature considered representative of the oceanic mixed layer temperature that is typically represented by any sea temperature measurement within the upper ocean o…

definition: The sea surface skin temperature is the temperature measured by an infrared radiometer typically operating at wavelengths in the range 3.7 - 12 micrometers. It represents the temperature within the conductive diffusion-dominated sub-layer at a depth of approximately 10 - 20 micrometers below the air-sea interface. Measurements of this quantity are subject to a large potential diurnal cycle including cool skin layer effects (especially at night under clear skies and low wind speed conditions) and warm layer effects in the daytime.

definition: The Common Sense Climate Index (Hansen et al. 1998) is a simple measure of the degree (if any) to which practical climate change is occurring. The index is a composite of several everyday climate indicators. It is expected to have positive values when warming occurs and negative values for cooling. If the Index reaches and consistently maintains a value of 1 or more, the climate change should be noticeable to most people who have lived at that location for a few decades.

With the additionof other components (such as a sea ice model or a model for evapotranspirationover land), the AOGCM becomes the basis for a full climate model. Some recent models include the biosphere, carbon cycle and atmosphericchemistry as well. AOGCMs can be used for the prediction and rate of change offuture climate. They are also used to study the variability and physicalprocesses of the coupled climate system. Global climate models typically have aresolution of a few hundred kilometres. Climate projections from the HadleyCentre make use of the HadCM2 AOGCM, developed in 1994, and its successorHadCM3 AOGCM, developed in 1998. Greenhouse-gas experiments with AOGCMs haveusually been driven by specifying atmospheric concentrations of the gases, butif a carbon cycle model is included, the AOGCM can predict changes in carbondioxide concentration, given the emissions of carbon dioxide into theatmosphere. Similarly, an AOGCM coupled to an atmospheric chemistry model isable to predict the changes in concentration of other atmospheric constituentsin response to climate change and to the changing emissions of various gases.Further information is available on: some aspects of ocean simulation in HadCM3(thermohaline circulation, ventilation, vertical mixing), decadal variabilityin the ocean of HadCM3. Recently a global coupled climate model with an eddy-permitting oceanresolution has been developed at the Hadley Centre, in order to betterrepresent important oceanic processes.

definition: Deuterium Oxide is a stable, non-radioactive isotopic form of water, containing 2 atoms of deuterium (D) and one atom of oxygen (2D2O), with DNA-labeling activity. Upon ingestion of deuterium oxide, 2H is incorporated into the deoxyribose moiety of DNA of newly divided cells. Rapidly dividing cells, as in the case of B-cell chronic lymphocytic leukemia (B-CLL), can be labeled with deuterium oxide and measured using gas chromatography and/or mass spectrometry.

definition: Molecular hydrogen H2 is an attractive candidate as future energy carrier because combustion of H2 produces H2 O only. In addition to saving the CO2 emissions (if the H2 is formed from carbon-free energy sources), also the massive energy-related emissions of other compounds like carbon monoxide, nitrogen oxides and soot could be drastically reduced, leading to improvements in air quality (Schultz et al., 2003). Nevertheless, unavoidable leakage in the production, distribution, storage and consumption of H2 could drastically alter the mixing ratio of H2 in the atmosphere. Although it is not a greenhouse gas itself, H2 affects the atmospheric lifetime of the greenhouse gas methane and many other species via its reaction with the hydroxyl (OH) radical (Schultz et al.,2003). In addition, H2 is an important source for stratospheric water vapor, which provides the substrate for polar stratospheric clouds that play a key role in the formation of the stratospheric polar ozone hole. Therefore, increasing levels of H2 in the atmosphere will counteract the predicted recovery of the ozone hole (Tromp et al., 2003; Warwick et al.,2004; Feck et al., 2008).

reference:
  text: https://the-cryosphere.net/12/2175/2018/
definition: Glacio-hydrological models (GHMs) allow us to develop an understanding of how future climate change will affect river flow regimes in glaciated watersheds. A variety of simplified GHM structures and parameterisations exist, yet the performance of these are rarely quantified at the process level or with metrics beyond global summary statistics. A fuller understanding of the deficiencies in competing model structures and parameterisations and the ability of models to simulate physical processes require performance metrics utilising the full range of uncertainty information within input observations. Here, the glacio-hydrological characteristics of the Virkisá River basin in southern Iceland are characterised using 33 signatures derived from observations of ice melt, snow coverage and river discharge. The uncertainty of each set of observations is harnessed to define the limits of acceptability (LOA), a set of criteria used to objectively evaluate the acceptability of different GHM structures and parameterisations. This framework is used to compare and diagnose deficiencies in three melt and three run-off-routing model structures. Increased model complexity is shown to improve acceptability when evaluated against specific signatures but does not always result in better consistency across all signatures, emphasising the difficulty in appropriate model selection and the need for multi-model prediction approaches to account for model selection uncertainty. Melt and run-off-routing structures demonstrate a hierarchy of influence on river discharge signatures with melt model structure having the most influence on discharge hydrograph seasonality and run-off-routing structure on shorter-timescale discharge events. None of the tested GHM structural configurations returned acceptable simulations across the full population of signatures. The framework outlined here provides a comprehensive and rigorous assessment tool for evaluating the acceptability of different GHM process hy…
