摘要： 气象卫星遥感海面温度的资料处理关键环节是云检测(筛选晴空区)和大气削弱订正。目前卫星气象中心的卫星海面温度处理业务系统中,针对美国的NOAA 卫星是利用国际上普遍使用的红外窗区多通道法。对于中国发射的风云一号(FY-1)气象卫星,由于星载辐射计只有一个红外窗区通道能用于大气削弱订正,为此专门开发了单通道海面温度处理方法。文章介绍了两种方法的基本原理、算法和处理结果举例,并对两种方法的特点作了简要评价。

Abstract: For the remote sensing of Sea Surface Temperature(SST)by the meteorological satellite,the keys of data processing are cloud testing and correction of atmospheric attenuation.The current method used in the SST processing system of Chinese Satellite Meteorology Center is the multi-cha- nnel statistical regressive method which has been generally used in the world for NOAA satellite data.But as the radiometer on the Chinese FY-1 sate- llite has only one infrared window channel,Satellite Meteorology Center has to develop a statistical estimation method.This paper briefly introduces the fundamental principles,computation methods and processing results by using these methods and reviews the characteristics of the two methods.
