A partial coherent model of brightness temperatures of polar ICE sheets at l band incorporating multi-layer roughness effects based on SPM2 theory

Effect of roughness on forward physical model for Brightness Temperature of Antarctic ice sheets is presented. The Antarctic ice sheet which is characterized by layers of ice with permittivity fluctuations in addition to random rough interfaces. In order to investigate effect of roughness on brightness temperature, we only consider top 20 layers of ice sheets rough and all other layers with flat interfaces. The comparison between the results of the model and ESA's soil moisture ocean salinity (SMOS) brightness temperature show that the influence of roughness can significantly increase horizontally polarized thermal emission while leaving vertically polarized emissions relatively unaffected.
