Scattering of atmospheric millimeter wave radiation by spherical particles

Scattering of microwave atmospheric and terrestrial surface radiation on dielectric particles suspended in the air can significantly modify atmosphere brightness temperature´s angular distribution and cause some polarization effects. In this paper, radiative transfer calculations are used with a thin cloud model and a simple vertical thin cloud parallel to the surface, that is based on assumptions of spherical particle shape and homogeneous underlying surface. This simple model makes it possible to reveal interesting spectral and angular features caused by such phenomena and at the same time can be useful for description of microwave propagation under some realistic conditions
