A Simple Chemical Cloud Model: Can Simplicity Approximate Reality?
Abstract
An important aspect of the redistribution and transformation of trace gases within the atmosphere concerns the occurrence of clouds. The flow pattern associated with clouds can transport trace gases from regions with high concentrations (normally the boundary layer) to relatively clean regions e.g. the free troposphere, (Ching 1989 and Builtjes 1988). Rain transports atmospheric constituents to the earths surface, primary those components which have an affinity towards liquid water. The introduction of an aqueous phase changes the air chemistry. Soluble species will be absorbed by the aqueous phase which prohibits them to participate in the gas phase chemistry (Lelieveld 1990). Some transformations occur at higher rates within the aqueous phase when compared to the rates in the gas phase, e.g. the oxidation of SO2 to sulphate.
