Short summary

Sulfate is a key species contributing to particle formation and growth during wintertime Chinese haze events. This study combines observations and modeling of oxygen isotope signatures in sulfate aerosol to investigate its formation mechanisms, with a focus on heterogeneous production on aerosol surface via H₂O₂, O₃, and NO₂ and trace metal catalyzed oxidation. Contributions from different formation pathways are presented.
