Abstract: Based on the long wave radiation data from FY-3A/MERSI and MODIS data with 1 km resolution, the land surface temperatures (LST) in 10 sunny days or local sunny days from April to September in 2009 and 2010 were retrieved using a generalized single-channel method in Liaoning province. The results indicate that the verified accuracy of model is consistent with that of MODIS LST products from NASA, and the values of LST agree well with the observational values from 56 weather stations. The retrieval of LST is more reliable because of the combination of multi-source remote sensing data. The difference of LST is significant in the different land use/cover types in the same time. The correlations between LST and NDVI in forest, paddy field, dry land and building are negative. The relationships between LST and land use/cover types, LST and NDVI could be analyzed by the remote sensing and GIS technology.
