Short summary
The oxidation of SO2 directly by NO2 on solid/liquid particles is proposed to be a major pathway of particle sulfate formation in the polluted atmosphere. We found that the reaction of SO2 and NO2 on CaCO3 particles produced Ca(NO3)2 aqueous droplets, providing a site for the multiphase oxidation of SO2. The direct multiphase oxidation of SO2 by NO2 led to a reactive uptake coefficient of SO2 on the order of 10-8, which is unlikely to be an important source of sulfate in the ambient atmosphere.
