SIMULATION OF A MULTILAYER MODEL OF DENSE SCATTERERS FOR ANOMALOUS SCATTERING SIGNATURES FROM SSM I SNOW DATA/

Numerical simulation of coupled vector radiative transfer equations fo r a multi-layer model of dense scatterers is developed. The effect fro m ice layer formed during melting is studied to take account of anomal ous spectrum of brightness temperature at the SSM/I channels. This app roach is applied to analysis of SSM/I data observed over the southern and central Greenland snow, which can show distinctly different spectr al characteristics, T-B19 > T-B85 or T-B19 < T-B85. Ice layers produce d in melting and ice grain sizes can significantly affect functions of thermal emission at SSM/I channels.
