Outline of Final Research Achievements |
A new-type aerosol transport model (NICAM-Chem) in hybrid scales covering from global to regional areas was developed for properly simulating PM2.5 distribution in Asia. The simulated PM2.5 components of both primary particle of black carbon (BC) and secondary particle of sulfate were generally comparable to the observations in monthly mean values. Especially, the high-resolution simulations give a better performance of simulating diurnal variations in aerosol due to meso-scale phenomena. A model intercomparison using NICAM and different dynamic model, MIROC, quantified the differences in simulating sulfate and PM2.5 caused by the difference in simulating cloud fields. A comparison in BC and sulfate between NICAM-Chem and different transport model, WRF-CMAQ, with the observations were conducted. These results clarify the uncertainties of models, which is an important message to properly simulate PM2.5 distribution.
