Abstract: Satellite remote sensing has played a critical role in the quantitative retrieval of atmospheric PM2.5, which can be attributed to its advantages of wide spatiotemporal coverage and low cost. This paper reviews the progress of remote sensing mapping of atmospheric PM2.5. First, the atmospheric PM2.5 remote sensing retrieval methods are summarized, and the applicable conditions and limitations of the validation approaches for atmospheric PM2.5 remote sensing retrieval are analyzed. Second, this paper summarizes the bias correction of satellite retrieved PM2.5 synthesis product and the missing information reconstruction of satellite retrieved PM2.5. Finally, the prospective directions of remote sensing mapping of atmospheric PM2.5 are discussed.

Key words: atmospheric PM2.5 mapping, satellite remote sensing, satellite and ground fusion, accuracy validation, gapless monitoring
