Accuracy Evaluation of FY-3A/MERSI Aerosol Optical Depth Data in Beijing and Its Adjacent Region
Automatic aerosol observation network (AERONET) and FY-3A Moderate Resolution Imaging Spectrometer (FY-3A/MERSI) are matched by utilizing the method of band interpolation and temporal-spatial matching. The inversion precision of FY-3A/MERSI AOD products in Beijing, China and adjacent regions is verified and analyzed by using AERONET AOD data. The results show: (1) FY-3A AOD data presents a high relativity (R=0.733) with AERONET AOD data and generally less than it (bias=-0.012). (2) The higher the underlying surface vegetation coverage is, the higher the FY-3A AOD data retrieving accuracy is, and the accuracy in winter-spring season is higher than that in summer-autumn season. Also, the retrieval precision is greater in low aerosol concentration condition. The above conclusions can provide reference for the application of FY-3A/MERSI aerosol products in northern China.
