气象卫星资料对积雪的遥感监测与分析

Monitoring and Analyzing Snow Cover with Meteorological Satellite Remote Sensing Data

概述了 NOAA气象卫星积雪遥感监测的基本原理和国内几种积雪遥感监测的方法 ,较详细地介绍了积雪监测方法。以 1 998年 6月 2日祁连山区积雪遥感监测和 1 998年祁连山区疏勒河流域逐旬积雪遥感监测为例介绍了此方法应用情况。通过对山区积雪与邻近气象站降水资料的分析发现测站降水量与后一旬的雪深、雪面积相关性较好。

This paper introduces the basic principle of NOAA satellite data monitoring snow cover and sums up its methods used in China, and based on which an improved way is put up. With this method Qilian Mountain snow cover in 2 June,1998 and ten\|days snow cover over Shulehe river basin in 1998 were monitored. The results shows that this method is available and last ten days snow depth and area is correlated to the precipitation observed at weather station.
