用8.0~9.3μm遥感数据反演地温的分裂窗算法性能分析
Performance analysis of split-window algorithms for retrieving land surface temperature using remote sensing data of 8 . 0~9 . 3 μm
摘要
Abstract
Spaceborne wide-field imaging spectrometer sets up two channels, CH18(8. 125 ~8. 825 μm) and CH19 (8. 925~9. 275 μm) for retrieving land surface temperature. To verify the adaptability of the traditional split-window algorithms applied to the atmospheric window of 10~14μm for the atmospheric window of 8. 0~9. 3μm, the authors introduced three kinds of split-window algorithms, i. e. , Sobrino,Franca & Cracknell and Becker, with the parameter calculation formulae being revised against band setting for split-window in atmospheric window of 8. 0~9. 3 μm, and verified the retrieved accuracies of land surface temperature by the six standard atmospheric models supplied by MODTRAN. The results show that the present 3 kinds of split-window algorithms fail to meet the land surface temperature precision requirement of less than 1K and are not suitable for direct transplantation.关键词
