| environ. | air conditioning A system or process for controlling the temperature and sometimes the humidity and purity of the air in a house, etc. | luftkondisjonering |
| scub. | air-integrated dive computer | Luftintegrert dykkecomputer |
| gen. | air mattress | luftseng |
| environ. | air movement Air movements within the Earth's atmospheric circulation; also called planetary winds. Two main components are recognized: first, the latitudinal meridional component due to the Coriolis force (a deflecting motion or force discussed by G.G. de Coriolis in 1835. The rotation of the Earth causes a body moving across its surface to be deflected to the right in the N hemisphere and to the left in the S hemisphere); and secondly, the longitudinal component and the vertical movement, resulting largely from varying pressure distributions due to differential heating and cooling of the Earth's surface | luftbevegelse |
| environ. | air pollutant Any pollutant agent or combination of such agents, including any physical, chemical, biological, radioactive substance or matter which is emitted into or otherwise enters the ambient air and can, in high enough concentrations, harm humans, animals, vegetation or material | luftforurensende stoff |
| environ. | air pollution Presence in the atmosphere of large quantities of gases, solids and radiation produced by the burning of natural and artificial fuels, chemical and other industrial processes and nuclear explosions | luftforurensning |
| scub. | air pressure | Lufttrykk |
| gen. | air pump | luftpumpe |
| environ. | air quality The degree to which air is polluted; the type and maximum concentration of man-produced pollutants that should be permitted in the atmosphere | luftkvalitet |
| environ. | air quality control The measurement of ambient air-pollution concentrations in order to determine whether there is a problem in a given region | luftkvalitetskontroll |
| environ. | air quality management Regulate and plan and work toward the accomplishment of completion of stated goals, objectives and mission pertaining to air quality | luftkvalitetsforvaltning |
| environ. | air quality monitoring Regular checking and recording of air quality in a given area. The following pollutants must be considered: carbon monoxide, benzene, butadiene, lead, sulphur dioxide, nitrogen dioxide, and particulates | luftkvalitetsovervåking |
| environ. | air safety Any measure, technique or design intended to reduce the risk of harm posed by either moving vehicles or projectiles above the earth's surface or pollutants to the earth's atmosphere | luftsikkerhet |
| environ. | air temperature The temperature of the atmosphere which represents the average kinetic energy of the molecular motion in a small region and is defined in terms of a standard or calibrated thermometer in thermal equilibrium with the air | lufttemperatur |
| environ. | air traffic Aircraft moving in flight or on airport runways | lufttrafikk |
| environ. | air traffic law International rules and conventions relating to air transportation | lufttrafikklovgivning |
| environ. | air traffic regulation | lufttrafikkforskrift |
| environ. | air transportation The use of aircraft, predominantly airplanes, to move passengers and cargo | lufttransport |
| light. | air-turbo lamp | trykkluftlampe |
| environ. | air-water interaction The physical processes at the air-water interface: momentum, heat and mass transfer across the air-water interface, mixing of surface water by wind stress and wave breaking, directional wave spectra and wave forces on offshore structures. The air-water interaction is measured by the turbulence and gas exchanges resulting from the mixing of the water column by wind | luft/vanninteraksjon |
| PSP | ambient air temperature | omgivelsestemperatur |
| environ. | civil air traffic Air traffic pertaining to or serving the general public, as distinguished from military air traffic | sivil lufttrafikk |
| environ. | clean air area Areas where significant reductions in ozone forming pollutants have been achieved through industrial initiatives to control and/or prevent pollution, through implementation of transportation improvement plans, national efforts to reduce automobile tailpipe emissions and lower the volatility (evaporation rate) of gasoline | område med ren luft |
| environ. | clean air car Vehicles that function without emitting pollutants in the atmosphere | miljøvennlig bil |
| light. | compressed air luminaire | trykkluftlampe |
| el.gen. | compressed air power station | trykkluftskraftstasjon |
| el.gen. | compressed air storage | trykkluftsmagasin |
| environ. | gaseous air pollutant Uncondensed or volatile gases, usually comprised of chemical compounds, discharged to the atmosphere | luftforurenser i gassform |
| environ. | indoor air pollution Chemical, physical or biological contaminants in the air inside buildings and other enclosed spaces occupied by humans. This pollution can arise from tobacco smoke, pesticides, cleaning agents, gases released from building materials, rugs, household products, etc. | forurensning av inneluft |
| environ. | military air traffic Air traffic of or relating to the armed forces | militær lufttrafikk |
| environ. | ocean-air interface The sea and the atmosphere are fluids in contact with one another, but in different energy states - the liquid and the gaseous. The free surface boundary between them inhibits, but by no means totally prevents, exchange of mass and energy between the two. Almost all interchanges across this boundary occur most effectively when turbulent conditions prevail. A roughened sea surface, large differences in properties between the water and the air, or an unstable air column that facilitates the transport of air volumes from sea surface to high in the atmosphere. Both heat and water (vapor) tend to migrate across the boundary in the direction from sea to air. Heat is exchanged by three processes: radiation, conduction, and evaporation. The largest net exchange is through evaporation, the process of transferring water from sea to air by vaporization of the water | grenseflate mellom hav og luft |

| environ. | respiratory air Air volumes inspired and expired through the lungs | respirasjonsluft |
| environ. | soil air The air and other gases in spaces in the soil; specifically that which is found within the zone of aeration. Also known as soil atmosphere | jordluft |
| environ. | waste air Exhaust or gaseous air given off by any industrial, manufacturing or chemical process | fraluft |
| environ. | waste air purification gas | fraluftsrensing |
