loud Chemistry Modeling: Parcel and 3D Simulations

The interaction of gases and aerosol particles with clouds entails a number of key environmental processes. On the one hand, they directly influence the life cycles of trace constituents and facilitate conversions of these trace constituents. On the other hand, multiphase transformations strongly influence cloud formation. Over a long time, the complexities of the cloud processes involved have discouraged investigators from simultaneously treating all aspects of multiphase chemistry and microphysics with equal rigor. Many recently available models focus either on complex multiphase chemistry only in a few aggregated drop classes (Ervens et al., 2003; Herrmann et al., 2000), or detailed microphysics for strongly simplified chemical mechanisms (Bott, 1999).
