Short summary
Based on continuous measurement at the SORPES statin in Nanjing, eastern China, we report the trend of PM2.5 and relevant chemical species there during 2011–2018. We found significant reduction of PM2.5 in both winter and early summer due to emission reduction of fossil-fuel combustion and open biomass burning, respectively. Reduction of fossil-fuel combustions contributed to 76 % of the wintertime PM2.5 decrease, with the remaining 24 % being caused by the change of meteorology.
