In this study, an experimental observation using the ground-based microwave radiometer for Oats was carried out in order to understand the microwave characteristic of vegetation effect. First, vegetation parameter, single scattering albedo and vegetation's fractional area were calculated using the observed data, and the reliability of experimental observation's result was checked by the comparison with an observed microwave brightness temperature and a calculated brightness temperature based on the calculated vegetation parameter and single scattering albedo. Furthermore, the estimation method of snow depth in snow cover area over the North Eurasia was investigated based on the calculated vegetation parameter, single scattering albedo and vegetation's fractional area. In the result, the estimation accuracy of snow depth was improved by the introduction of vegetation's fractional area based on the mix-pixel model.
