Short summary
We present the evolution of tropospheric aerosols over Wuhan, central China, from 2010 to 2024. The analysis highlights the long-term aerosol characteristics and separates natural (dust) and anthropogenic (non-dust) contributions. Emission control policies were highly effective during 2010–2017. However, since 2018, lidar-derived aerosol optical depth (AOD) ceased decreasing and fluctuated, and the decline in PM2.5 concentration also became slower, possibly due to atmospheric chemistry factors.
