Thermal radiation Transfer through the rain atmosphere in successive order scattering

In the present work, the authors carried out a theoretical assessment of the thermal radio emission and precipitation intensity and polarization when observed by microwave radiometers from space. We propose to apply the method of successive order of scattering to simulate the microwave radiation of atmospheric clouds and rain. The authors carry out numerical modeling of the transfer of thermal radio emission in the rain atmosphere at a number of wavelengths. We have shown the effectiveness of the method and the solutions obtained in comparison with the finite difference method. It is shown that successive orders of scattering has a significant advantage for solving the tasks set.
