Our observed results show that the dramatic NO(x) decrease (77%) led to significant O(3) increases (a factor of 2) during the COVID-19 lockdown in megacity Hangzhou, China. Model simulations further demonstrate large increases of daytime OH and HO(2) radicals and nighttime NO(3) radical, which can promote the gas-phase reaction and nocturnal multiphase chemistry. Therefore, enhanced NO(3) (-) and SO(4) (2-) formation was observed during the COVID-19 lockdown because of the enhanced oxidizing capacity. The PM(2.5) decrease was only partially offset by enhanced aerosol formation with its reduction reaching 50%. In particular, NO(3) (-) decreased largely by 68%. PM(2.5) chemical analysis reveals that vehicular emissions mainly contributed to PM(2.5) under normal conditions in Hangzhou. Whereas, stationary sources dominated the residual PM(2.5) during the COVID-19 lockdown. This study provides evidence that large reductions in vehicular emissions can effectively mitigate air pollution in megacities.
