Two-Stream Parameterization of the Flux Divergence in a Plane-Parallel Atmosphere.

Abstract

Accurate two-stream representation of the angular distribution of radiation exchange in a plane-parallel atmosphere requires the use of a diffusivity factor at least 13% larger than the normally chosen values of 1.66 or sq. rt. 3 (approx. = 1.732), since the flux divergence, rather than the transmitted flux, determines the heating or cooling rates. Diffusivity factors are calculated to yield exact results at various optical depths for Doppler and Lorentz line profiles as well as for the grey-absorption case. (Author)
