A radiometric term for the rate at which radiant energy in a set of directions confined to a unit solid angle around a particular direction is transferred across unit area of a surface (real or imaginary) projected onto this direction.
The radiance per unit wavelength or wavenumber interval.
Solar radiation absorbed by the atmosphere's constituent gases, suspended material, clouds, or by the earth's surface.
The total electromagnetic radiation emitted by the sun.
In radiation, the net flux of radiation into or out of a system. As a consequence of radiative forcing there must be some change to the nonradiative energy states of the system.
Radiant energy per unit time passing some specified area from one side.
>Heat flux averaged over a layer of air, such as the boundary layer; heat-flux divergence or difference between the top and bottom of a layer.
Longwave radiation originating by thermal emission from a planetary surface and/or its atmosphere
The extinction coefficient for a particular substance is a measure of how well it scatters and absorbs electromagnetic radiation (EM waves). If the EM wave can pass through very easily, the material has a low extinction coefficient. Conversely, if the radiation hardly penetrates the material, but rather quickly becomes extinct within it, the extinction coefficient is high.
