Simulating Microwave Emission from Antarctica Ice Sheet with a Coherent Model

A multi-layer electromagnetic model (Microwave Model Emission Snow Ifac - Multilayer Coherent, MIMESI-MC) based on Wave Approach, Strong Fluctuation Theory and Fluctuation-Dissipation Theorem was employed to investigate the microwave emission features of Antarctica ice sheet at DOME C. The inputs to the electromagnetic model were derived from a glaciological model describing the firn properties, such as density, mean grain size and temperature, as a function of depth. Obtained results were compared with space-borne observations, and a sensitivity analysis was performed. Lastly, L-band brightness temperature was computed, as a function of the observation angle and of the day of the year. The latter simulation pointed out the high stability of the low frequency emission.
