| environ. | atmospheric aerosol Particulate matter suspended in the air. The particulate matter may be in the form of dusts, fumes, or mist. Aerosols in the atmosphere are the form in which pollutants such as smoke are dispersed | atmosfærisk aerosol |
| environ. | atmospheric chemistry The study of the production, transport, modification, and removal of atmospheric constituents in the troposphere and stratosphere | atmosfærekjemi |
| environ. | atmospheric circulation The general movement and circulation of air, which transfers energy between different levels of the atmosphere. The mechanisms of circulation are very complicated. They involve the transfer of energy between the oceans and the atmosphere, the land and the atmosphere, as well as the different levels of the atmosphere | atmosfæresirkulasjon |
| environ. | atmospheric component The Earth's atmosphere consists by volume of nitrogen (79,1%), oxygen (20,9%), carbon dioxide (about 0,03%) and traces of the noble gases (argon, krypton, xenon, helium) plus water vapour, traces of ammonia, organic matter, ozone, various salts and suspended solid particles | atmosfærisk komponent |
| environ. | atmospheric composition The chemical abundance in the earth's atmosphere of its constituents including nitrogen, oxygen, argon, carbon dioxide, water vapour, ozone, neon, helium, krypton, methane, hydrogen and nitrous oxide | atmosfærisk sammensetning |
| environ. | atmospheric correction The removal from the remotely sensed data of the atmospheric effects caused by the scattering and absorption of sunlight by particles; the removal of these effects improves not only the quality of the observed earth surface imaging but also the accuracy of classification of the ground objects | atmosfærisk korreksjon |
| environ. | atmospheric emission Suspended pollutants -- solid particles, liquid aerosols, etc. -- or toxic gases released into the atmosphere from a polluting source, or type of source | utslipp til luft |
| environ. | atmospheric fallout The sedimentation of dust or fine particles from the atmosphere | atmosfærisk nedfall |
| environ. | atmospheric humidity A measurable quantity of the moisture content found in the earth's atmosphere | luftfuktighet |
| environ. | atmospheric inversion A temperature inversion in the atmosphere in which the temperature, instead of falling, increases with height above the ground. With the colder and heavier air below, there is no tendency to form upward currents and turbulence is suppressed. Inversions are often formed in the late afternoon when the radiation emitted from the ground exceeds that received from the sinking sun. Inversions are also caused by katabatic winds, that is cold winds flowing down the hillside into a valley, and by anticyclones. In inversion layers, both vertical and horizontal diffusion is inhibited and pollutants become trapped, sometimes for long periods. Low-level discharges of pollutants are more readily trapped by inversions than high level dischargers, hence the case for high stacks. Furthermore, high level discharges into an inversion tend to remain at a high level because of the absence of vertical mixing | atmosfærisk inversjon |
| environ. | atmospheric layering Any one of a number of strata or layers of the earth's atmosphere; temperature distribution is the most common criterion used for denoting the various shell. Also known as atmospheric shell; atmospheric region | atmosfærisk lagdeling |
| environ. | atmospheric model A simulation, pattern or plan designed to demonstrate the structure or workings of the atmosphere surrounding any object, including the Earth | atmosfæremodell |
| environ. | atmospheric monitoring A practice of continuous atmospheric sampling by various levels of government or particular industries | luftovervåking |
| environ. | atmospheric ozone A triatomic molecule of oxygen; a natural constituent of the atmosphere, with the highest concentrations in the ozone layer or stratosphere; it is found at a level between 15 and 30 km above the Earth, which prevents harmful ultraviolet B radiation, which causes skin cancer and threatens plant life, from reaching the ground. The fragile shield is being damaged by chemicals released on Earth. The main chemicals that are depleting stratospheric ozone are chlorofluorocarbons (CFCs), which are used in refrigerators, aerosols and as cleaners in many industries and halons, which are used in fire extinguishers. The damage is caused when these chemicals release highly reactive forms of chlorine and bromine | atmosfærisk ozon |
| environ. | atmospheric particulate A concentration of fine liquid or solid particles, such as dust, smoke, mist, fumes or smog, found in the atmosphere | atmosfærepartikkel |
| environ. | atmospheric physics The study of the physical phenomena of the atmosphere | atmosfærefysikk |
| environ. | atmospheric pollution The presence in the air of one or more contaminants in such a concentration and of such duration as to cause a nuisance or to be injurious to human life, animal life or vegetation | atmosfærisk forurensning |
| environ. | atmospheric precipitation The settling out of water from cloud in the form of dew, rain, hail, snow, etc. | nedbør (meteorologisk fenomen) |
| scub. | atmospheric pressure | Atmosfærisk trykk |
| environ. | atmospheric process Atmospheric processes are distinguished in physical and chemical processes and both types may be operating simultaneously in complicated and interdependent ways. The physical processes of transport by atmospheric winds and the formation of clouds and precipitation strongly influence the patterns and rates of acidic deposition, while chemical reactions govern the forms of the compounds deposited | atmosfærisk prosess |
| environ. | atmospheric science The atmospheric sciences study the dynamics, physics and chemistry of atmospheric phenomena and processes, including the interactions of the atmosphere with soil physics, hydrology and oceanic circulation. The research focuses on the following areas: turbulence and convection, atmospheric radiation and remote sensing, aerosol and cloud physics and chemistry, planetary atmospheres, air-sea interactions, climate, and statistical meteorology | atmosfærevitenskap |
| environ. | atmospheric structure The gaseous area surrounding the planet is divided into several concentric spherical strata (layers, like shells) separated by narrow transition zones. The boundaries are know as "pause". More than 99% of the total atmospheric mass is concentrated in the first 40 km from the Earth's surface. Atmospheric layers are characterized by differences in chemical composition that produce variations in temperature | atmosfærisk struktur |
| light. | atmospheric transmissivity | atmosfærisk transmissivitet |
