A method for the retrieval of aerosol optical thickness on CBERS data from top-of-atmosphere radiance

A method for the retrieval of aerosol optical thickness on China-Brazil Earth Resources Satellite (CBERS) data has been introduced. This algorithm is designed to estimate precise Aerosol Optical Thickness (AOT) only using Visible to Near-infrared spectral bands (400–900nm) information. The first part of this paper is devoted to the description of this method; outline the main steps in this correction process. The validation task is detailed in the second part. Many groups of simulated data was used to validate this algorithm, the R-squared equals to 0.98 and the RMSE equals to 0.052 shows the method has a good performance. Then an image of CBERS was selected to validate this method. The surface reflectance after atmospheric correction is much closer to the real spectrum.
