摘要：

For vegetated surface. the commonly used soil moisture retrieval algorithm is a zero-order model which might not be the best one for AMSR-E. since multiple scattering effects could not he ignored at higher frequencies. But due to the simplicity of the zero-order model. it still. has the advantage in SM retrieval. except emission relationship between different frequencies of AMSR-E of both hare surface and vegetation exist. In this paper. a new method to retrieve SM for AMSR-E more accurately is proposed based on emission simulation of bare surface at C, X- and Ku-band Die unknown variables elimination in retrieval is by finding the relationships of single scattering albedo (and optical opacity) of vegetation scatter between same frequency ranges.
