Snow is an extremely important natural element of land surface, and the study on snow parameters inversion is of great significance to research and application of related areas. On the basis of the current research results, the advantages and disadvantages of snow remote sensing data were compared and analyzed, and the rationality and inadequacy of snow inversion by using remote sensing data were discussed in this paper. Firstly, the current remote sensing platform series for snow remote sensing inversion were briefly introduced. Secondly, the advantages and disadvantages of optical sensors and microwave remote sensing instruments were discussed, and the importance of combination of the two kinds of image data to snow inversion study were emphasized. Meanwhile, the application progress of optical sensors such as moderate resolution imaging spectroradiometer and advanced very high resolution radiometer to calculate snow area, map snow cover etc was mainly introduced, and the present development situation of snow depth calculation, snow water equivalent estimation etc by utilizing passive microwave sensors such as advanced microwave scanning radiometer, specific microwave sensor/imager and multichannel microwave scanning radiometer was reviewed. In addition, the important position of active microwave remote sensing sensor in the study of snow remote sensing in the future was also mentioned. Finally, the problems needed to pay attention to and deficiencies in current study of snow remote sensing were summarized and discussed.
