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.

区域尺度气溶胶输送模式(RAMS/CFORS和CMAQ)被用于分析在ACE-Asia试验期间在日本4个偏远岛屿观测到的黑碳。模式分析表明，黑碳在北部站点和南部站点之间的时空分布处于不同的流态下。1998年和2004年的多年CMAQ模拟相当成功，模式结果与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变化和年际变化提供了重要信息。我们将沿着以下方向继续我们的研究：(1)建立网站公开野外观测小组的模式结果；(2)通过引入嵌套能力来扩展模式研究，并在日本周围进行类似的多年水平分辨率20公里模拟；(3)基于IPCC AGCM/RAMS气象学和FRCGC 2020排放清单的2020年CMAQ模拟，以检查东亚地区的03和其他污染水平。
