Air pollutants and aerosol species for China in December 2016

The dataset contains: 1) 24h-average surface PM2.5 mass concentrations routinely measured at 1153 national air quality monitoring stations in China; 2) comprehensive measurements at four supersites in YRD, namely Dian Shan Lake (DSL; 31.1ºN, 121.0°E), Pudong (PD; 31.2º N, 121.5°E), Nanjing (NJ; 32.1ºN, 119.0°E) and Hangzhou (HZ; 30.3ºN, 120.2°E). They provided hourly concentrations of aerosol fine particles (PM2.5), water-soluble ions (sulfate, nitrate, ammonium and other ions), carbonaceous aerosols (EC and organic matter (OM)) and gaseous pollutants (SO2, NO2, carbon monoxide (CO) and ozone (O3)). The dataset covers the period from 1 to 24 December, 2016.
