Light intensity in disperse layers: Computation based on the reduction of disperse layers characterized by a strongly asymmetric scattering phase function to an anisotropic medium

A procedure for solving the radiative transfer equation (RTE) is considered . This procedure is based on representing the zero azimuthal harmonic (ZAH) of the scattering phase function as a combination of a smoothed ZAH and a Dirac delta -function. Unlike the conventional transport approximation, the coefficient of the delta -function depends on the angular variable. This f act makes it possible to achieve a better agreement between the properties of the smoothed ZAH and the potentialities of the quadrature formulas appli ed to solve the RTE and also to improve the computation accuracy. The appli cation of the procedure to media characterized by the scattering phase func tion typical of clouds is considered.
