Aerosol optical depth (AOD) data set is an important parameter to measure aerosol radiation effect and study the temporal and spatial distribution, total amount of atmospheric conditions and their impact on global climate. The use of polar orbiting satellites for high-frequency monitoring of global aerosol distribution is limited by the number of satellites and the scanning width of satellites (determined by the field of view and height of satellites), which can not meet the needs of atmospheric environment observation with high time resolution. Professor Xue Yong, academician of the International Eurasian Academy of Sciences, leading his teammates, cooperated with domestic and foreign universities, made lots of scientific exploration and the research results formed the paper "Joint Retrieval of Aerosol Optical Depth and Surface Reflection over Land Using Geostationary Satellite Data" and “Deriving a Global and Hourly Data Set of Aerosol Optical Depth Over Land Using Data From Four Geostationary Satellites: GOES-16, MSG-1, MSG-4, and Himawari-8”,published in the Journal of IEEE Transactions on Geoscience and Remote Sensing,2019 and 2020.
