Based on characteristics of the CBERS image and the theory of the atmospheric radioactive transfer model and using MODTRAN as the core of the algorithm, the authors established the aerosol optical depth search table to correct the atmospheric influence. This means can meet the needs of operational quantitative products of CBERS, and can also yield fairly good application effects, as was evidenced by using the CBERS image in the atmospheric correction along the Gailingjiang River valley of Guangyuan in Sichuan Province on August14, 2005.
