| Research Abstract |
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.
