Abstract
The long-range transport of air pollutants from other continents has been found to have great effects upon regional air pollution. To account for the influence of continental transport, boundary conditions (BC) from a Global Chemistry Model (GCM) have been used in a limited-domain air quality model (i.e., CMAQ and CAMx) to provide real-time chemical flux through the boundaries. In the recent past, various GCMs have been available for regional air quality studies, including GEOS-chem, WRF-Chem, CHASER and IFS-CB05 MACC. In this study, we cross-compared three GCM models in the year of 2010 for what we labelled the “East Asia domain” using CMAQ under the MISC-ASIA, and HTAP Jointed experiments; the afore mentioned were provided by Seoul National University for GEOS-Chem; Nagoya University for CHASER and ECWMF for IFS CB05 MACC. All CMAQ results are tabulated to provide insight about the model comparison of these GCMs for regional application and to demonstrate how the influence of boundary condition selection affects the regional simulation in East Asia.
