Analysis of melting particle model and microwave and mm-wave scatterings due to a melting layer of precipitation

In this paper, the water-coated snow sphere model of melting particles has been given, Based on this model, the scattering properties and albedo w(0) of melting particles have been calculated by use of the coated sphere BHCOA T 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 albe do 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 w ith the conclusion radar observed and literature given([1,2]). It demonstra tes that the water-coated snow sphere model of melting particles is appropr iate and practicable. The study is significant for the utilization of the l ow fade margin system in satellite communication.
