Short summary
Based on field observations of N2O5, we found extremely high nighttime concentrations of N2O5, with a maximum value of 2.52 ppb. Further multiphase box model analysis revealed that the heterogeneous uptake of N2O5 is the most significant nitrate formation pathway in NO2-limited urban areas. Additionally, we further analyzed the reasons for this high N2O5 uptake contribution, and discussed the synergistic reduction of nitrates and O3.
