A group of reference calibration coefficients for China-Brazil earth resource satellite(CBERS)-02′s CCD data were attained by cross calibration method using LANDSAT-5′s TM data. A method based on meteorological information and ATCOR3 was used in the atmospheric correction of CBERS-02′s CCD four bands. The definition of image and normalized difference vegetation index (NDVI) before correction were compared with them after correction. The result shows that after atmospheric correction the image contrast is enhanced,the mean of NDVI is obviously improved and the difference of NDVI between vegetation and nonvegetation is increased. When the underlying surface is rugged terrain,the corner angle of mountain is distinct,the profile is clear and the original shape is recovered,which benefits the extract of remote sensing information.
