Abstract
Global Land Data Assimilation System (GLDAS) is often used as a test bed for innovative modeling and assimilation capabilities. So its reliability is very important, the validation and the evaluation of product from GLDAS often use in-situ observations. Now remote sensing has been an important observation source, but satellite observations have not directly relation with the output of GLDAS, their relationships are so complex even fuzzy with many parameters. This study analyzed the reliability of soil moisture and land surface temperature simulated by GLDAS using Advanced Microwave Scanning Radiometer-Earth Observing System (AMSR-E) data for the periods of one year based on fuzzy comprehensive evaluation theory, Results demonstrate that both of them are relatively believable, and the land surface temperature is more reliable than the soil moisture.
