Short Description

Using the modelled output of the radiative transfer, calculate the atmospheric correction coefficients.

The atmospheric correction coefficients are required for computing Lambertian reflectance.  The coefficients are given as follows:

S = Atmospheric albedo
TV = Total transmittance in the view (observer) direction
TS = Total transmittance in the solar diection
fV = Direct fraction in the view (observer) direction
fS = Direct fraction in the solar direction
A = (Dir + Dif) / Pi * TV
B = Path radiance
Dir = Direct irradiance at the surface
Dif = Diffuse irradiance at the surface
