. Heterogeneous reactivity of N2O5 on aerosols isa critical parameter in assessing NOx fate, nitrate production, andparticulate chloride activation. Accurate measurement of its uptakecoefficient (γN2O5) and representation in air quality modelsare challenging, especially in the polluted environment. With an in situaerosol flow-tube system, the γN2O5 was directly measured onambient aerosols at two rural sites in northern and southern China. Theresults were analyzed together with the γN2O5 derived fromprevious field studies in China to obtain a holistic picture ofN2O5 uptake and the influencing factors under various climatic andchemical conditions. The field-derived or measured γN2O5 wasgenerally promoted by the aerosol water content and suppressed by particlenitrate. Significant discrepancies were found between the measured γN2O5 and that estimated from laboratory-determined parameterizations.An observation-based empirical parameterization was derived in the presentwork, which better reproduced the mean value and variability of the observedγN2O5. Incorporating this new parameterization into a regionalair quality model (WRF-CMAQ) has improved the simulation of N2O5,nitrogen oxides, and secondary nitrate in the polluted regions of China.
