Influence of atmospheric in-cloud aqueous-phase chemistry on the global simulation of SO₂ in CESM2 [PDF]

Atmospheric Chemistry and Physics, 2021
Sulfur dioxide (SO2) is a major atmospheric pollutant and precursor of sulfate aerosols, which influences air quality, cloud microphysics, and climate. Therefore, better understanding the conversion of SO2 to sulfate is essential to simulate and predict ...
