Retrieval of Land Surface Temperature from Landsat 8 for the Main Urban Area of Kunming

Abstract

Based on Landsat 8 TIRS 10 data, using the radiative transfer equation (RTE) and the improved mono-window algorithm (TIRS_SC) to retrieve the land surface temperature (LST) for the main urban area of Kunming, and compare the accuracy of the two methods. Then use the high precision method to retrieve LST of the main urban area of Kunming in 2013-2015. Results showed that RTE is more suitable for retrieval LST in the main urban area of Kunming. The LST of most area in Wuhua District and Guandu District is higher, and the low LST is mainly the Dian Lake and other region where there is water.
