Abstract :
In this paper, the retrieval of aerosol over land surfaces from CCD data of China Brazil Earth Resources Satellite (CBERS) 02B was studied. The method is dark dense vegetation (DDV) algorithm: 1) dense vegetation (dark pixel) was recognized by the NDVI threshold; 2) the look up table (LUT) of atmosphere was computed from the Satellite Signal in the Solar Spectrum (6S) model; 3) the aerosol was retrieved through interpolating the LUT by CCD data. The method was applied to Beijing area, and the retrieved aerosol was validated by ground-based measurements of CE318. The result shows that from CBERS02B data, the aerosol can be retrieved well.
