Influence of the variation in inflow to East Asia on surface ozone over Japan during 1996–2005
Graduate School of Environmental Studies, Nagoya University, Nagoya, Japan
Abstract. Air quality simulation in which global and regional chemical transport models are coupled has been developed to investigate the influence of the variation in inflow to East Asia on the interannual variability and the long-term trend of surface ozone over Japan during 1996–2005. The simulation overestimates the concentration of surface ozone from summer to early winter. It is deduced that ozone formation around Northeast China is overestimated in the simulation. On the other hand, the simulation reproduces the interannual variability and the long-term trend of observed surface ozone over Japan well. Results of sensitivity experiments suggest that inflow to East Asia accounts for approximately 30% of the increasing trend of surface ozone, whereas it has much less influence on the interannual variability of observed surface ozone compared to meteorological processes within East Asia.
