摘要
对气象卫星观测角的影响进行纠正可提高气象卫星资料的可用性。在分析气象卫星ＮＯＡＡ／ＡＶＨＲＲ数据的几何特征的基础上，提出了一种基于信息比重之上的分级分段加权平均对ＮＯＡＡ／ＡＶＨＲＲ观测角影响进行纠正的方法。将气象卫星资料的使用范围从±１４°扩大至±２７°。
Correction of the meteorological satellite viewing angle effects can improve the utilization of meteorological satellite information.With the analysis of the g eometrical features of meteorological satellite NOAA/AVHRR data,the paper sugges ts a grading weighted averages method for correcting NOAA/AVHRR viewing angle ef fects on the basis of information proportion,which has been proved to be success ful in practical.This will extend the use of meteorological satellite data from ±14° to ±27°.
