COMPLETE SCATTERING PARAMETERS OF POLYDISPERSED HYDROMETEORS IN THE 0.1 TO 10 CM RANGE,

Abstract

The extinction, the albedo of single scattering, the differential scattering cross section, and the complete polarization properties, per unit volume of cloud and rain elements, irradiated by microwave radiation at various frequencies were determined. Continuous dropsize distribution functions are introduced to represent real clouds and precipitation, and the absorption and scattering parameters are integrated with high accuracy. A Rayleigh approximation is found adequate for the cloud model, but the complete Mie expressions had to be used for precipitation-sized particles. Older estimates were corroborated, but some new features were brought out for the first time, such as the scattering intensity and polarization (including its ellipticity) as a function of scattering angle.
