Short summary
Using polarization lidar observations during 2010–2024, we retrieve the vertical profiles of aerosol backscatter and extinction coefficients of anthropogenic pollution under dry and ambient atmospheric conditions over central China. The year-to-year and seasonal variations in anthropogenic AOD are largely changed after removing hygroscopic growth effect.
