| 概要 | Long-term synergetic fine and coarse mode aerosol observations were analyzed at 1-h intervals at the Chikushi-campus of Kyushu University, Fukuoka, Japan, from December 2013 to March 2015. The GEOS-Ch...em chemical transport model, including dust and sea-salt acid uptake processes, was used for detailed analysis of observation data. Long-range anthropogenic aerosol trans-boundary transport events were observed during our analysis period, and the numerical model generally captured the observed time variation of PM_〈2.5〉 aerosols. In order to have a better understanding of trans-boundary PM_〈2.5〉 contribution, the model domain was divided into 15 major source regions, and emission intensity sensitivity analysis was conducted to show the detailed source-receptor relationship. We found the Japanese domestic contribution to annual averaged PM_〈2.5〉 concentration at Fukuoka was 20 %, and another 80% were coming from outside Japan (19.6 % and 16.3% were coming from central north China region and Korea, respectively). From late fall to early spring when the PM_〈2.5〉 concentration became higher, the trans-boundary fraction reached up to 90%, and this fraction was higher when the daily PM_〈2.5〉 concentration exceeded the environmental standards of 35μm/m^3.続きを見る |
