Short summary
Surface PM2.5 concentrations can be enhanced by aerosolradiation interactions (ARIs) and aerosolcloud interactions (ACIs). In this study, we found  PM2.5 enhancement induced by ACIs shows a significantly smaller decrease ratio than that induced by ARIs in China with anthropogenic emission reduction from 2013 to 2021, making ACIs more important for enhancing PM2.5 concentrations. ACI-induced PM2.5 enhancement needs to be emphatically considered to meet the national PM2.5 air quality standard.
