Aerosol is an important index in atmosphere monitoring. Disadvantages exist when monitoring aerosol from HJ-1 data by dark dense vegetation （DDV） or contrast reduction algorithm. In this paper

based on the algorithm which was developed by Hsu

et al.（2004）

the deep blue algorithm is applied to CCD/HJ-1. First

the database of land surface reflectance is built from MODerate-resolution Imaging Spectroradiometer （MODIS） spectral reflectance product. Second

after analyzing relationship between CCD camera reflectance and MODIS

the reflectance of MODIS are corrected to CCD camera of HJ-1. Third

aerosol optical depth （AOD） is retrieved from apparent reflectance in the first band of CCD/HJ-1. Finally

AODs over Beijing area are retrieved from December 2008 to October 2009

and the results are validated by ground-based measurement of Beijing station in the PHOtométrie pour le Traitement Opérational de Normalisation Satellitaire （PHOTONS） network included in the worldwide Aerosol Robotic Network （AERONET）. The validation and discussions show that

when AODs are greater than 0.5

the accuracy of deep blue algorithm can satisfy the aerosol monitoring using HJ-1 data

and aerosol model can greatly influence the results.
