Short summary
Year-long observations of PM2.5, gaseous pollutants, and meteorological parameters in Beijing were analysed to investigate sulfate formation. RH and O3 concentrations above thresholds of 45 % and 35 ppb, respectively, greatly accelerated sulfate formation. Ambient changes in RH and O3 contributed to variations in sulfate formation among different seasons and pollution levels. A shift from gas-phase to multiphase SO2 oxidation contributed to fast sulfate formation under polluted conditions.
