Incorporation of the Canadian aerosol module into a unified regional air quality modelling system

摘要

The Canadian aerosol Module [CAM] is being incorporated into a new, multi-pollutant, multi-issue Eulerian regional air quality modelling system -AURAMS [AES Unified Regional Air-Quality Modelling System]-whose first application will be to simulate particulate matter [PM] emissions, transport, chemistry, and removal in eastern North america. CAM employs a size-distributed multi-component aerosol algorithm and has been used in Canadian climate models to assess the climatic impact of atmospheric aerosols. In addition to CAM, AURAMS will contain an emissions pre-processor, a metorological driver, and a chemical transport model, including gas- and aqueous-phase chemistry and removal processes for gaseous species.
