The heterogeneous hydrolysis of dinitrogen pentoxide (N2O5) is an important pathway in nitrate formation; however, its formation rate and relative contribution to total particulate nitrate (pNO3-) are highly variable. Here we report that nocturnal pNO3- formation via N2O5 hydrolysis is dependent on the regime defined by the ratio of NO2 to O3. Nocturnal pNO3- formation via N2O5 hydrolysis is suppressed in an O3-limited regime but enhanced in a NO2-limited regime. The results have crucial implications for effective control of nitrate pollution in the future. An exclusive decrease in NO2 will decrease nocturnal pNO3- formation in a NO2-limited regime but may be less effective or even increase nocturnal pNO3- formation in an O3-limited regime.
