Short summary
The reaction of SO2 with NO2 on particles is proposed to be one major pathway of sulfate formation in the polluted atmosphere. We found that in the reaction of SO2 with NO2 on CaCO3 particles, presence of O2 enhanced the uptake rate of SO2 by 2–3 orders of magnitude compared with the reaction of SO2 directly with NO2. O2 was the main oxidant of SO2 and NO2 was the initializer of chain reactions. The multiphase oxidation of SO2 by NO2/O2 can be an important source of sulfate in the atmosphere.
