Extinction Coefficient
Definition
It is a measure of attenuation of the light passing through the
atmosphere due to the scattering and absorption by aerosol particles.
Extinction coefficient is the fractional depletion of radiance
per unit path length (also called attenuation especially in
reference to radar frequencies). It has units of
km-1. The integrated extinction coefficient over a
vertical column of unit cross section is called aerosol
optical depth or optical thickness.
