%X We proposed a new atmospheric correction approach for HJ-1 CCD datasets, in which the aerosol optical depth (AOD) is acquired based on the relationships between surface refl ectance of the blue band and red band over dense dark vegetation (DDV) regions. The atmospheric correction look-up tables (LUTs) were introduced to provide atmospheric correction coefficients under different aerosol loadings and sun-view geometry. The comparison of the results with intraday MODIS (Moderate Resolution Imaging Spectroradiometer) surface refl ectance out-puts (MOD09) indicated the proposed atmospheric correction method has preferable accuracy. We did uncertainty analyses from the aspects of AOD retrieval accuracy, radiometric calibration accuracy, altitude impact and atmospheric water vapor con-tent impact.
