Wet Scavenging Parameterization in the Oxidant Version of a Three Dimensional, Global Atmospheric Chemistry-Transport-Deposition Model

摘要

We have developed a three-dimensional, oxidant model, GRANTOUR, that predicts, among other species, tropospheric OH and O3 (Atherton et al., 1990). The model simulates a number of chemical and physical processes, including source emissions, chemical reactions, transport, and wet and dry deposition. Traditionally, global model parameterize wet deposition. This report compares wet scavenging rates, n, in the literature to those currently used in the oxidant version of GRANTOUR.
