摘要：
In this paper, using revised Chang's algorithm and SSM/I 37GHz and 19GHz horizontally polarized brightness temperature, we retrieved the snow depth distribution in Qinghai-Xizang (Tibet) plateau, assessed the results' accuracy, and analyzed its error sources. It showed that Chang's algorithm could describe the general trend of snow depth distribution in this area, in spite of overestimation in parts of the area. The errors are mainly from the effect of the existence of permafrost, depth-hoar and vegetation cover. The coarse spatial resolution of SSM/I remotely sensed data make the retrieved snow depth hard to compare with the ones from ground observation, make it difficult to evaluate the accuracy.
