在MODIS数据对CBERS-02卫星CCD相机的交叉辐射定标、获得CCD相机时间系列的辐射定标斜率系数与截距基础上，本文考虑地物BRDF特性的影响，开展了提高CCD相机数据定量化应用的辐射定标数据精度的研究，并提供了比较全的时间系列辐射定标系数。

In our previons study radiometric cross-calibration forCCD camera usingMODIS data, and they\ngave the radiometric coefficients and offsetswere given. However, the calibration precision of those calibration\ncoefficients is not so good, since the BRDF of the calibration sites was not considered. What’smore, the\ncalibration coefficients for tmi e series ofCCD data are lmi ited because calibrationswere performed for the pairs\nof mi ages ofwhich the viewing zenithsoftheMODIS are smaller than 30°. The effortofthe article is to enhance\nthe calibration precision of calibration coefficients for CCD data by considering the BRDF of the calibration\nsites. Andmore complete calibration coefficients for tmi e series ofCCD data are intended to be provided.
