(1) Nitrate was a dominant contributing species in water-soluble inorganic ions during the high PM2.5 events in Nanjing.
(2) Nitrate aerosols in Nanjing during the PM2.5 events were mainly produced by hydrolysis of N2O5 in preexisting aerosols under ammonium-rich regimes.
(3) Control in NOx emissions would inhibit production of nitrate aerosols since NH4NO3 formation was HNO3 limited in Nanjing.
