| 英文摘要: | Aerosol Modeling System (AMS) that is consisted of the Asian Dust Aerosol Model2 (ADAM2) and the Community Multi-scale Air Quality (CMAQ) modeling system has been employed to document the geographical distributions of both the annual averaged Asian dust aerosol and the anthropogenic aerosols concentrations and their total depositions in the East Asia region for the year 2010. It is found that AMS simulates quite well the monitored PM10 concentration with a root mean square error (RMSE) of 9.2μgm-3 and a normalized mean square error (NMSE) of 5.5% in South Korea and the RMSE of less than 33μgm-3 with a NMSE of less than 7.8% at the monitoring sites in China. The annual mean surface (column integrated) aerosol concentrations in the East Asia region affect in a wide region as a complex mixture of the Asian dust (AD) aerosol and the anthropogenic aerosol (AA), more predominated by the AD aerosol in the Asian dust source region of northern China and Mongolia with the annual mean (column integrated) PM10 concentration of more than 200μgm-3 (350mgm-2). Whereas AA is dominated in the high pollutant emission regions of southern and eastern China and northern India with the annual mean surface (column integrated) concentration of more than 110μgm-3 (140mgm-2) in eastern China. On the other hand the mixed aerosols (AD+AA) are dominated in the downwind regions of the Yellow Sea, the East China Sea, the Korean peninsula, Japan, and the Northwest Pacific Ocean. It is also found that the annual total deposition of aerosols in the model domain is 4.9×108t (3.7×108t by AD aerosol and 1.2×108t by AA), of which 66% (3.2×108t) is found to be contributed by the dry deposition (3.1×108t by AD aerosol and 1.3×107t by AA) and 34% (1.7×108t) by the wet deposition (1.0×108t by AA and 6.6×107t by AD aerosol), suggesting significant impacts of aerosols on environment and the terrestrial and marine eco-systems in East Asia. © 2015 Elsevier Ltd. |
