Short summary
Particulate nitrate is a growing issue in air pollution. Based on comprehensive field measurement, we show heavy nitrate pollution in eastern China in summer. OH reacting with NO2 at daytime dominates nitrate formation on clean days, while N2O5 hydrolysis largely enhances and become comparable with that of OH reacting with O2 on polluted days (67.2 % and 30.2 %). Model simulation indicates that VOC : NOx  = 2 : 1 is effective in mitigating the O3 and nitrate pollution coordinately.
