Abstract
In recent years,with rapid development of remote sensing technology,algorithms to retrieve land surface tempera?ture using image have been proposed constantly. In order to study the application of surface temperature inversion under the condi?tion of Landsat8 image,in this study,using two SW algorithms(Juan C.Jimênez-Mu?oz and Offer Rozenstein SW algorithms)and Qin Zhihao mono-window algorithm of surface temperature inversion over the region of Changsha City based on July 23,2016 Land?sat8 image data,and combined with MODIS surface temperature products to verify the results. The results show that:the minimum temperature difference of two SW algorithms which have an error of 1.49k,the maximum temperature difference of 1.04K, mono-window algorithm compared with the two SW algorithm,the minimum temperature difference of 2.12K,0.63K,the maximum temperature difference of 1.52K,3.56K,and the minimum temperature of three algorithms compared to MODIS temperature prod?ucts which have error on-0.79K,0.7K,1.33K,The accuracy of the two SW algorithms is better than mono-window algorithm.关键词
