A More Important Role for the Ozone-S(IV) Oxidation Pathway due to Decreasing Acidity in Clouds.xlsx

In this study, a multi-year period observation campaign of clouds at the summit of Mt. Tai was conducted. The chemical compositions of cloud water samples were measured and the S(IV) oxidation rates in cloud were analyzed. This study highlights the long-term characteristics and variation of chemical species in cloud at Mt. Tai. The high ambient O3 and the increase of aqueous phase pH made O3 pathway dominant the S(IV) oxidation in cloud at Mt. Tai.
