Short summary
Over East Asia, the transboundary air pollution of SO42− has been recognized. The importance of the transboundary air pollution of NO3 in winter was demonstrated in this study through synergetic ground-based observations with state-of-the-art measurements of secondary inorganic aerosols (SO42−, NO3, and NH4+) and a regional chemical transport model analysis. This study will help to refine the understanding of transboundary heavy PM2.5 pollution in winter.
