### radiative transfer

**(RT)**
(energy transfer in the form of electromagnetic radiation)

**Radiative transfer** is the transfer of energy via
electromagnetic radiation (EMR) through a gas or plasma, in particular,
for a gas not so transparent that EMR merely misses all impediments.
For such a less-than-transparent gas, absorption, emission,
and scattering of the constituent atoms are basic to the process.

Radiative transfer is characterized by
the quantity radiance,
the rate of energy flowing at a given time
through a given area at a given location.
**Spectral radiance**, in turn, is the radiance
at a given wavelength.

An equation of radiative transfer is an equation that describes this process,
relating the transmission of energy to quantities
characterizing the likelihood of absorption,
emission, and scattering.
