【Abstract】 The calculation method and monitoring model of the snow cover information are introduced, by characterizing the short infrared waves and using the remote sensing data of the FY-1D meteorological satellite, which was released by the 9210 meteorological program. In addition, a new method is introduced to monitor the depth and the area of the snow cover by remote sensing, illustrated by the remote sensing monitor of the snow cover in Xinjiang from November 2002 to May 2003. The characteristics of the snow cover and the pattern of the snow cover variation are also analyzed with this method.更多还原
