| Research Abstract |
Emission control of green house gases may be the most serious issue in the 21st century. However, attitude to this issue is not necessarily consistent among countries in the world. One reason may be attributed to uncertainly in science and modeling for future prediction on the effect of human activity on atmospheric environment in global scale. Thus, we have tried to develop a comprehensive Global Scale Chemical Transport Model (GCTM) in this study. The model can take into account (1) rapid increase of fossil fuel consumptions, (2) biomass fire caused by agricultural activity, (3) aircraft emission in lower stratosphere, (4) CH_4 emission from rice paddy, natural wet land, and animals, (5) NO_x emission by lightning activity, (6) biogenic hydrocarbon emission, (7) emission from active volcano, etc. The model includes the major processes of transport (advection, diffusion, sub-grid scale cumulus convection), chemistry (gas and liquid phase chemistry), and wet- and dry-deposition. The developed GCTM was applied to investigate the effects of biomass fire in Indonesia and Australia, and lightning on ozone etc. in low-latitudinal area. The model showed its applicability by successfully simulating TOMS ozone enhanced by biomass fire activity in the area.
