| Abstract: | Snow depth is an important parameter in snow monitoring.How to select the charactersitic parameter and construct model is one of the key issues in snow depth retrieval using remotely sensed images.In this paper,MODIS images over Tianshan region were used,from which 37 potential retrieval variables were pre-selected,and ten days in-situ snow depth data of seven in-situ observations were used for analysis,Gray system theory,which has the advantage of multi-variable analysis of the small samples was selected t... |
