Impact of Long Transport on Taiwan’s Ozone Air Quality from East Asia

Abstract:

To clarify the influence of air pollutants emitted from East Asia on the ozone air quality in Taiwan, this study performs a long-term simulation result for 4 months using Taiwan Air Quality Model. Influence from the current (2007) and future (2020) East Asian emissions on the ozone concentration in Taiwan were simulated. The date ranges simulated were February, May, August, and October of 2007, representing the seasons of winter, spring, summer, and autumn. Influence from transboundary transport on Taiwan was assessed based on simulations of these 4 months. The influence of transboundary transport on the monthly average of daily peak ozone concentrations in Taiwan is 15.5 ppb. Worst case scenarios in 2020 will contribute an additional 3.7 ppb. If the size of ozone pollution area (≧120 ppb) is considered, transboundary transport contributed to 72 % of the polluted area in 2007; the ozone pollution area in the worst case scenario in 2020 will further increase by 47 % from 2007 levels.
