Abstract As an important parameter governing energy balance over land, Land Surface Temperature (LST) plays an
important role in meteorology, hydrology, ecology and some other disciplines. In this paper, the authors have
analyzed the probable sources of errors in retrieving land surface temperature using MODIS data and dealt in detail
with the validation method for simultaneous retrieval using relatively high resolution remote sensing data. A
comparison between ASTER land surface temperature and MODIS LST products was conducted in Taihu area on August 1,
2003. Linear regression of three typical areas in water surface, city ground, and outskirts of Wuxi respectively
shows that the result is satisfactory for validation, with R2 being 0.9666.
