Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a satellite remote sensing monitoring method, device and computer-readable medium for air pollution. Background technique [0002] Atmospheric pollution environmental control has been paid more and more attention by departments at all levels, and there are various monitoring methods and methods for monitoring atmospheric PM particles using satellite remote sensing. As the most basic parameter of atmospheric aerosol optical characteristics, aerosol optical depth (AOD) is the integral of the aerosol extinction coefficient from the ground to the top of the atmosphere, which characterizes the degree of extinction caused by aerosol scattering in the vertical column of cloudless atmosphere, which is different from that of the atmosphere It is related to the aerosol mass concentration, extinction coefficient and hygroscopic growth parameters. At present, satellite remote sensin...
