Retrieving Lst and Its Thermal Environment Evaluation Analysis Based on Cbers-02 Irmss and Modis Data

The thermal environment and thermal effect is one of the most important contents in city climate and environment researches. Retrieving and analyzing land surface temperature (LST) is an efficient way to research thermal environmental problem of earth surface. Taking Fuzhou as the study area, this paper uses CBERS-02 IRMSS thermal infrared remote sensing data for generalized single-channel algorithm developed by Jiménez-Munoz and Sobrino to inverse surface temperature. MODIS data received on the same day was used to compute the atmospheric water vapour content in the pixel scale which is a important parameter for the algorithm. Based on the results of the inversion, we introduce the human body comfort index to evaluate the urban thermal environment of Fuzhou by revising its evaluation system. The results show that the combinations of multi-satellite remote sensing data can the accuracy of the surface temperature inversion. And the HCI method can be effectively used to describe the quality of urban thermal environment. * Corresponding author. [email protected]
