Electromagnetic radiation (for instance, thermal radiation in the infrared range) may be attenuated in passing. The albedo ω is the dimensionless value that is equal the ratio of scattering coefficient (β) to the sum of absorption (k) and scattering (β) coefficients:

The single scattering albedo defines the fraction of energy scattering in total energy attenuation. The dependencies of ω on frequency and temperature are determined by the corresponding dependencies of k and β. Albedo is widely used in radiative heat transfer calculations.
