Abstract
Air pollution is a serious environmental problem. Aerosol. which plays an important role in regional air pollution. is the main source of it. To get information of aerosol accurately and quickly, remote sensing image retrieval is an effective way. Sources of aerosols are different. Anthropogenic activity is the main factor causing thick aerosol. In that way, how to extract effective anthropogenic activity data to characterize aerosol and its influence becomes a significant scientific issue. In order to solve this problem, this paper uses HJ satellite remote sensing images and near IR-visible surface albedo correlation approach to retrieve aerosol optical depth (AOD). We also analyzed the relationship between the AOD and population density. The conclusion is as follows: (1) The spatial resolution of AOD retrieved from HJ satellite image is higher than that of the MODIS results. (2) There is a high correlation between AOD distribution and population density in the research region of east China. The correlation coefficient between population density value and the AOD is R-2 = 0.625. (3) To most of the cities, the beta value is larger than 1. This means that the aerosol level increases incrementally from small to larger populations in cities.
