Abstract
This study developed a satellite algorithm for snow depth and snow grain size basedon the microwave radiative transfer theory used the dense media model and the 4-stream fast model and validated by using the in-situ snow depth data at the 75 ground-based stations in the northern hemisphere and the Advanced Microwave Scanning Radiometer for the Earth Observation System (AMSR-E) on Aqua launched by NASA in 2002. The results of validation were show good correspondence of observation value and estimation value.
