| Summary: | Abstract A multi-layer electromagnetic model 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 (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. |
