Abstract

AbstractRecently, nitrate (NO3) levels in winter pollution in eastern China have been increasing yearly and have become the main component of PM2.5. The factors contributing to this rise in surface NO3 concentrations remain unclear, complicating the development of targeted pollution control measures. This study utilizes observational data from Shanghai during the winter 2019, alongside box model simulations, to recreate the NO3 pollution event and identify the key factors in the growth process. The analysis demonstrated that a rise in winter ozone levels significantly promotes NO3 production by facilitating NOx conversion via gas-phase and heterogeneous reactions. These findings could explain the correlation between the synchronous increase of surface ozone and NO3 in recent years. Furthermore, simulation of control strategies for NOx and volatile organic compounds (VOCs) identified an approach centered on ozone reduction as notably effective in mitigating winter NO3 pollution in the Yangtze River Delta.
