    Abstract:
    AMSR-E soil moisture products have been gradually used in meteorology, agriculture and other fields. Studying soil moisture has important significance, especially in arid and semiarid regions. In order to investigate AMSRE soil moisture products in Xilinhot grassland applicability, this paper utilizes field experiments in Xilinhot grassland, which is a 3 km× 3 km area within the AMSRE retrieval region with the same ninepoint latitude and longitude ground soil moisture compared to validate product precision. Because the relationship between precipitation and surface soil moisture is most closely, the soil moisture inversed from AMSR-E and precipitation data for comparison can validate soil moisture product reliability indirectly. Compared with the ground data, it shows that the AMSRE retrieval value and the groundbased measured average soil volumetric water content are 13.3% and 11.8% respectively, and their RMSE is 3.7%.
