Planck’s model for random discontinuous cloud fields generation in a three-dimensional computational domain is considered. An algorithm has been developed for computation a 2D picture of downwelling microwave radiation brightness temperature distribution from altitude profiles of the main meteorological parameters, including liquid water profile obtained during the generation of cloud field. The inverse problem of integral moisture content parameters distribution retrieval by means of dual-frequency method is solved. Systematic errors in the cloud liquid water content estimation associated with the use of a homogeneous flat-layered model of the cloud field, which ignores its real, inhomogeneous structure, are investigated.
