Outline of Final Research Achievements

Reproducibility of PM2.5 concentration due to implementations of updated anthropogenic and biogenic emissions and a new aerosol mechanism including the volatility basis set were evaluated for improving the prediction of atmospheric PM2.5 concentration. Concentration levels of organic aerosol have been improved and that slightly affected on PM2.5 concentration levels. However, reproducibility of the other species (ex. sulfate) was not necessarily improved.
