Short summary
We used ab initio calculations to explore a new path for ion-induced SO2 oxidation by ozone in the gas phase. We find that, initiated by the superoxide ion, SO2 can readily oxidize to SO3. The reaction is facilitated by the presence of water, being ~ 4 orders of magnitude faster than the reaction in the absence of water. Depending on the altitude and temperature, it is estimated that this reaction may contribute to 0.1–2.0 % of the total atmospheric sulfate.
