Many aerosol retrieval algorithms based on the remote sensing technology have been developed and applied to produce aerosol optical depth ( AOD) products for different satellite sensors. The dark target (DT) and deep blue (DB) algorithms are two main MODIS aerosol retrieval algorithms that are suitable for dark or bright areas. The estimation of land surface reflectance (LSR) is necessary to improve the accuracy of AOD retrievals. Therefore, in this paper, a new procedure to improve LSR estimation using MODIS surface reflectance products is developed. A new high-resolutionaerosol retrieval algorithm with a priori LSR database support (HARLS) is proposed. The purpose of this paper is to evaluate the spatial adaptability of different MODIS AOD products produced by the above three algorithms. The Beijing-Tianjin-Hebei (Jing-Jin-Ji) region, which features complex surface structures and serious air pollution, was chosen as the study area, and the different AOD products are validated using aerosol robotic network (AERONET) AOD ground measurements from four stations located in dark and bright areas. Comparedwith the DT retrievals (R approximate to 0.88 -0.95), the C6 DB AOD retrievals yield a stronger correlation (R approximate to 0.94 - 0.97) with AERONET AOD and lower RMSE, MRE and MAE values, resulting in approximately 20%-30% less average overestimation. The C6 DT& DBAODresults showa retrieval quality (R approximate to 0.93 - 0.97) similar to that of DB, with approximately 50%-70% of the collections falling within the expected error (EE). Moreover, DT& DB is much better than DT, with more than approximately 10%-20% of the collections falling within the EE. However, HARLS achieves a high correlation (R approximate to 0.93 - 0.96) with the AERONET AODs, with low RMSE (approximate to 0.118 - 0.128) andMAE (approximate to 0.09 - 0.12) and small offsets (intercept approximate to 0.00 -0.04). HARLS retrievals exhibited 7%-8% less uncertainty than the C6 DB retrievals, 37%-38% less uncertainty than the C6 DT& DB retrievals, and 39%-44% less uncertainty than the C5 and C6 DT retrievals. HARLS achieves greater accuracy and reliability in AODretrieval, and it is less biased(RMB approximate to 0.90 -1.10) and better overall than the routine MODIS aerosol products over the Jing-Jin-Ji region.
