Abstract

The numerical solution of radiative transfer equation including curvature with both absorption and scattering has been developed in the frame work of Discrete Space Theory. Two cases have been considered: (A) irradiation of the atmosphere at τ=T and (B) no irradiation on either side of the atmosphere. Isotropic scattering has been assumed. It is found that the emergent luminosities (defined by ∫r 2 I(r, μ) đμ) from scattering dominated atmospheres are smaller than those from absorption dominated atmospheres.
