The research history of retrieval of snow particle size remote sensing is introduced. The basis of remotely sensed inversion based on the principle of spherical or non-spherical hyperspectral reflection based on the high reflection of snow in the visible light band and the significant decrease of snow surface reflectance in the infrared region and the change of snow particle size , Including such as temperature, wavelength, particle shape, etc., and summarizes the models and algorithms used in the current study, pointing out its advantages and disadvantages.In addition, in order to obtain the accuracy of the particle size inversion, such as temperature, Wavelength, particle shape and other factors on particle size inversion and its verification method.
