英文摘要: Both ground and satellite observation of aerosol are short of long-term and wide covering data. Aerosol optical depth (AOD) retrieved by visibility data can partly make up the lack of long-term aerosol observation data. This article summaries the principle and progress of retrieval method in recent decades. Since Koschmieder firstly proposed the concept of daytime visibility and the empirical transformation formula between horizontal visual range and optical depth of atmosphere, the retrieval method has been gradually improved by many scholars considering the factors such as atmospheric scale height, the threshold value of human eye, the Rayleigh coefficient of atmospheric molecules, and the water vapor condition, etc. Spatial and temporal characteristics of retrieved results show that high AOD are distributed in large scale sand and dust area, central Europe, western Africa, southeastern North America and southeastern China and AOD in these areas continue to increase in recent decades. The comparison between the retrieved AOD and relevant satellite AOD in different periods and regions has well confirmed the accuracy of retrieval method, but the summary and discussion of visibility-retrieved AOD show that there are still many deficiencies to be improved. This paper also puts forward some feasible suggestions about how to improve the retrieval method from the consistency of visibility data modified visibility data using automatic observations, influence of water vapor, vertical profiles of aerosol particles, correction of retrieval results using satellite data, optimal solution of parameters and improvements through model simulation in the retrieval algorithm. © 2019 Elsevier B.V.
