Short summary
We statistically analyze the hygroscopic growth characteristics of urban anthropogenic aerosols over Wuhan, a megacity over central China, using lidar observations and Hänel parameterization from 2010 to 2024. Aerosol hygroscopic parameter γ increases from 2014 to 2017 and stabilizes at high levels afterwards, aligning with the changes in NO2-to-SO2 concentration ratio. Moreover, no evident differences are found across seasons, as well as between the free troposphere and boundary layer.
