| 摘 要： | 介绍了EOS／MODHS数据特点。通过对雪的光谱特征分析，提出利用归一化积雪被指数NDSI结合归一化植被指数进行积雪信息提取的方法。并以2004年2月7日云南省大面积降雪过程为例，分析和讨论了该次过程的范围和面积。结果表明：MODIS数据在云南省积雪监测方面有很好的应用前景。

| Abstract: | This paper introduced characteristic of EOS/MODIS data. By analyzing the spectrum characteristic of snow, a method of extracting snow information was suggested based on index of NDSI and NDVI. Taking snowfall on Feb.7, 2005 in Yunnan for an example, area of snow cover was calculated and discussed. The result showed that MODIS data is very suitable for snow monitoring in Yunnan. |
