| Abstract |
Heterogeneous reaction pathways involving water droplets in clouds and fogs are important mechanisms for chemical transformation of atmospheric trace gases. One of the fundamental parameters which determines the transfer rate of gases into aqueous droplets is the mass accommodation or 'sticking' coefficient for gas molecules on the droplet surfaces. The authors have developed a laboratory method for directly determining mass accommodation coefficients (y) and have applied it to SO2. The measurement indicates that SO2 transport into clean aqueous cloud and fog droplets will not be limited by interfacial mass transport under normal atmospheric conditions.
