Paper Abstract

A mathematical model and a Monte Carlo algorithm were developed to simulate radiation transfer in dispersive media that is optically anisotropic with respect to zenith angle of the light beam. The algorithm was created with the purpose to simulate radiation transfer processes in the atmosphere with optically anisotropic clouds (for instance, cirrus clouds). A numerical experiment was performed for a cloud with ice crystals of hexagonal cylinder shape. We compared results for scattering media with particles stochastically oriented in a horizontal plane and in space. It was shown that orientation of particles could strongly affect the albedo of clouds and the shape of halos.
