Numerical modeling of the long-range aerosol transport in Asia and the evaluation of dry/wet deposition processes

利用区域尺度气溶胶输送模式（RAMS/CFORS和CMAQ）对ACE-亚洲试验期间在日本4个偏远岛屿观测到的黑碳（BC）进行了分析。模型分析表明，北方站点和南方站点黑碳的时空分布处于不同的流态。对1998年和2004年的CMAQ模拟结果进行了比较，并与7年的O_3和CO观测资料进行了比较。模型结果为了解污染物浓度的季节和年际变化提供了重要信息。我们将在以下方向继续我们的研究，（1）建立网站，为实地观测组开放模式结果，（2）通过引入嵌套能力，并通过在日本周围进行水平分辨率为20 km的类似多年模拟，（3）基于IPCC AGCM/RAMS气象学和FRCGC 2020年排放清单的2020年CMAQ模拟，以检查东亚的03和其他污染水平。

The regional scale aerosol transport models (RAMS/CFORS and CMAQ) are used in the analysis of black carbon (BC) observed at 4 remote Japanese islands during the ACE-Asia experiment. Model analysis shows that the spatial and temporal distributions of black carbon between the northern sites and the southern stations are under different flow regimes. Multi-year CMAQ simulation from the year 1998 and 2004 was quite successful and model results are compared with the 7 year O_3 and CO observation data. Model results provide important information to understanding the seasonal and inter-annual pollutant concentration change. We will continue our research in the following directions, (1) establish the web site to open the model results for field observation groups, (2) extend the model study by introducing the nesting capability and by to make similar multi-years simulation with horizontally 20 km resolution around Japan, (3) CMAQ simulation for the year 2020 based on the IPCC AGCM/RAMS meteorology and FRCGC 2020 emission inventory to examine the 03 and other pollution level in East Asia.
