Description

The Boltzmann-Fokker-Planck (BFP) equation has been applied to treat the photon transport in highly anisotropic scattering media. Some benchmark cases relating to haze and cloud media have been investigated. It is found that, in general, the number of Legendre moments required for the BFP equation is a factor of --5 lower compared to that for the standard (discrete ordinates S/sub n/) approach for solving the Boltzmann equation for the comparable precision on the integral quantities like the albedo and transmission factor. But BFP is much more economical if one seeks precision on angular fluxes
