Validation of MODIS Aerosol Optical Depth Retrievals in Anhui Province

MODIS aerosol retrievals onboard Terra and ground truth data obtained from AERONET(Aerosol Robtic Network) solar direct radiance measurements are collocated to evaluate the quality of the former in Anhui. The validation results show that the MODIS Collection 005 aerosol optical thickness(AOT) has a good relationship with AERONET AOT and their correlation coefficient is larger than 0.8 in Anhui. MODIS Collection 005 AOT correspond with the error standard of NASA and most of its error can be controlled under ±0.05 ±0.15I„, so MODIS Collection 005 AOT is creditable in Anhui for science research.
