The radiometric calibration parameter is very important in quantitative application of remote sense data. In this paper, the Landsat Thematic Mapper Data of Beijing acquired in April 26, 2007 were applied to evaluating the radiometric calibration parameters supplied by USGS and RSGS. First, the radiance data were computed respectively with the calibration coefficients converted from calibration parameters.Second, the FLAASH atmosphere correction model was used to compute meteorological range and surface reflectance.Third, according to the aerosol observation data from AERONET and high resolution remote sensing image, the accuracy evaluation results of the two radiometric calibration parameters were obtained on the basis of the accuracy of meteorological range and classification of surface reflectance. The results show that parameters supplied by USGS can reflect radiometric features of TM sensor more accurately.
