    Abstract:   台灣為西太平洋邊緣的一個海島,與最近的中國大陸相距150多公里,過去研究結果顯示境外污染源對台灣酸沉降有重要的影響,在本研究中將討論境外污染源對台灣地面附近臭氧濃度的影響。
    Taiwan is an island located in the rim of West Pacific Ocean, apart from nearby Mainland China about 200Km. According to previous studies, transboundary pollutants have significant effects on the acid deposition in Taiwan. In this study, we will investigate the effects of transboundary pollutants on the ground-level ozone concentrations in Taiwan.
    The CAMx model was used for air quality simulations while RAMS was used to produce required meteorological input data. The emission data for Taiwan was obtained from TEDS. The emission data outside Taiwan was obtained from University of Iowa. Two episodes were selected for simulations from the air quality monitoring data of 2002.
    For the case of May episode, high ozone concentrations were occurred in the NW corner of Taiwan due to SE wind. The effects of transboundary pollutants on the ozone concentrations were noticeable in the boundaries of Taiwan, especially in the NW corner and southern Taiwan. If the emission sources outside Taiwan were omitted, the ozone concentration in NW Taiwan can reduce about 20ppb. For November episode, the areas significantly affected by transboundary pollutants include the boundaries of Taiwan and sea surface near Kaohsiung. The effects of transboundary pollutants on the NOx concentrations are unimportant.
