Mechanisms of sulphate aerosol production in clouds: effect of cloud characteristics and season in the Indian region

Measurements made during the Indian Ocean Experiment (INDOEX) in 1998, indicate likely regional atmospheric effects of sulphate aerosol over India including the potential for cloud processing of SO2 to sulphate. Sulphate aerosol production in clouds was examined for cloud characteristics and pollutant concentrations typical of the Indian region, to assess the contribution of different mechanisms to sulphate formation. A simple model was …
