Abstract
Three analytic models for calculating rain brightness temperature T br in the millimeter and centimeter wave bands are proposed. The choice of the radiation model required to calculate T br of the system formed by the atmosphere in the presence of precipitation and by the Earth’s surface is validated on the basis of the analysis of various physical processes affecting this radiation. These processes include absorption and scattering of radiation by hydrometeors as well as self-radiation and reflection from the Earth’s surface.
