A diurnal story of Δ17O($$\rm{NO}_{3}^{-}$$) in urban Nanjing and its implication for nitrate aerosol formation

Abstract Inorganic nitrate production is critical in atmospheric chemistry that reflects the oxidation capacity and the acidity of the atmosphere. Here we use the oxygen anomaly of nitrate (Δ 17 O( $$\rm{NO}_{3}^{-}$$ NO3− )) in high-time-resolved (3 h) aerosols to explore the chemical mechanisms of... View More
