Short summary

Over the past decade, the relative abundance of NH₄NO₃ in aerosol has been enhanced in most urban areas of China, which profoundly affects the PM_2.5 pollution episodes. Our work finds that fine-particle nitrate and ammonium exhibited distinct, different physicochemical behaviors in the aerosol aging process.
