用NOAA卫星AVHRR多通道数据确定地表类型

Determination of the Earth Surface Type by Using the AVHRR Data From NOAA

摘要: 本文介绍一种根据NOAA卫星AVHRR多光谱通道数据在三维数据空间r1-r2-r3的分布特性确定观测点下垫面类型的方法。下垫面类型分为云、植被、冰/雪、裸土、水五类，分类范围在10°—60°N、75°—150°E。从处理的结果与实时卫星云图对照来看，该方法是十分有效的。

Abstract: A method of determining the type daylight scene viewed by each resolution element of AVHRR is presented. The specification of the scene types is restricted to five categories: cloud, vegetation, non-vegetation land, ice/snow and water. The routine processing range is 10°—60°N, 75°—150°E. And, the output products were compared with the satellite cloud images at the same time. The results indicate that the method is sufficiently sensitive
