Analysis of Melting Particle Model and Microwave and MM-Wave Scatterings Due to a Melting Layer of Precipitation

Abstract

In this paper, the water-coated snow sphere model of melting particles has been given. Based on this model, the scattering properties and albedo w0 of melting particles have been calculated by use of the coated sphere BHCOAT method. It is shown that the albedo of melting particles may be more than the raindrops and snow spheres at 5 (C-band) and 14GHz (Ku-band). The albedo of melting particles are nearly less than the equivalent mass raindrops albedo at the Ka and mm-band of f > 20GHz. These results are in agreement with the conclusion radar observed and literature given[1,2]. It demonstrates that the water-coated snow sphere model of melting particles is appropriate and practicable. The study is significant for the utilization of the low fade margin system in satellite communication.
