A Three-Dimensional Cloud Chemistry Model

Abstract

A cloud chemistry model is formulated in term of continuity equations for chemical species in the aqueous and aqueous phases within the cloud. The model includes scavenging of SO₂, HNO₃, HN₃, H₂O₃, and sulphate aerosol particles. Calculations have been performed within the framework of a three-dimensional convective cloud model. The results are compared with aircraft measurements of cloud water chemistry.
