NOAA/AVHRR的分裂窗算法在地表温度反演中的应用

An Application of Split Window Algorithm to the Retrieval of Land Surface Temperature with NOAA/AVHRR Data

以吉林西部为研究区域,建立以NOAA/AVHRR卫星资料进行地表温度反演的参数化模型。利用2000年7月5日的AVHRR资料,在4种常见地表温度反演分裂窗算法的对比分析基础上,选用Coll和Caselles提出的分裂窗算法,获得研究区地表温度,为地表蒸发量遥感计算提供必要的地球物理参数。

Taking western Jilin Province as the study area, we build up a parameter model for the retrieval of land surface temperature from NOAA/AVHRR data, On the basis of comparative analyses of 4 conventional split window algorithms for surface temperature retrieval applied to AVHRR data on 5 July 2000,Coil and Caselles algorithm gives the best temperature estimation. The results are essential to the evaportranspiration estimation.
