AB: The UK's Global Model of Aerosol Processes (GLOMAP) is being developed to address several pressing problems: (1) to examine the processes controlling the global aerosol lifecycle; (2) to quantify changes in aerosol properties and distribution in response to anthropogenic emissions; (3) as a tool for the interpretation of field observations; and (4) as a benchmark model for developing parameterizations for the UK Hadley Centre's GCM, the Unified Model. GLOMAP is an aerosol microphysics and chemistry model based on the existing CTM TOMCAT, which has been widely used for tropospheric chemistry studies. Aerosols are simulated on a size bin grid and driven by processes of nucleation, condensation, coagulation, cloud scavenging etc. The aerosol module can be linked directly with the full tropospheric chemistry scheme in TOMCAT. In this presentation we show first results from GLOMAP, including several sensitivity experiments exploring the model's response to parameters such as nucleation rate, condensable vapor supply, and wet removal efficiency.
