| Abstract: | The method that to extract the snow cover with AVHRR data is introduced to drive the results automatically based on multi-spectral analysis.The percent of snow cover in Xinjiang, Inner Mongolia, Qinghai, Xizang and Northeast of China are calculated by using short period of snow cover data. The characteristic of snow cover in the west of China and its variation are analyzed. It is the supplemental in snow cover analyzing for the lack of snow cover information observed regularly by weather stations in the west of China. |
