| Abstract: | In this paper,the Jimenez-Munoz and Sobrino(JM&S) single-channel method was used for land surface temperature(LST) retrieval from HJ-1B IRS4 data for Zhuozhou and Gaobeidian,HeBei province,China,20 th May 2009.To ascertain whether the thermal infrared image of HJ-1B which has the similar sensor parameter and settings to Landsat 5 TM image is applicable for retrieving the land surface temperature,the retrieved LST results of two types of remote sensing images were compared.Based on the LST mapping results and corresponding statistic,an apparent trend could be observed which indicated the consistency in both LST value and its spatial distribution.Consequently,the performance of HJ-1B IRS serving as the data source for LST retrieval could be assessed with its feasibility. |
