亞洲大氣污染物 (例如，酸性污染物、沙塵暴、霾害、臭氧等) 之長程傳送於特定季節對臺灣空氣品質影響顯著。尤其以AQI 的角度，足以影響當前空氣污染防制成效評定。本計畫則透過科學方法檢視、掌握這些境外貢獻，以審慎評估空污政策之效益，並進一步掌握與解析短中期區域大氣污染物的變化及對臺灣空氣品質的影響，並達到預警效果，使大眾能有所警覺而自我防護，公部門亦能提早因應。本計畫主要探討東亞區域長期氣候變異、短期天氣型態及污染物排放對於臺灣空氣品質的影響，應用區域大氣及空氣品質模式系統，評估開發衛星反演技術與應用衛星資訊以評估與掌握境內外大氣污染物對臺灣空氣品質之影響程度；建立空氣品質預報及異常事件診斷之流程與作業方式及工具，強化緊急應變與決策之能力；以及運用前述工具進行即時性境外案例空氣品質預測及影響評估。此外，亦積極參與相關國際工作會議、活動或組織，與各國進行大氣與空氣品質模式技術交流及合作研究。

The long-range transport of regional atmospheric pollutants (acidic pollutants, dust, haze, ozone, etc.) has a significant impact on Taiwan's air quality during certain seasons. Especially from the aspect of AQI, it could affect the effectiveness of present air pollution control policies. A synergic approach of applying an atmospheric and air quality forecast modeling system, developing remote sensing techniques and using the satellite data has been established, in order to assess the impact of long-range transported pollutants on the air quality in Taiwan. This project also continues to explore long-term climate variability, short-term weather patterns, and pollutant emissions in East Asia, quantify the background concentrations of atmospheric pollutants in East Asia and Taiwan, and their contributions to transboundary pollution in Taiwan. In addition, the WRF/CMAQ numerical model is also applied to establish a regional atmospheric transport model system. Exploiting both of model system and satellite retrieval data to evaluate and predict the impact of local and transboundary atmospheric pollutants in Taiwan. The outcome of the project will further establish the operational methods and tools for air quality forecast and abnormal event diagnosis which can strengthen the ability of emergency response and decision-making. Besides, the project also actively expands and participates in international collaboration and is in line with the current international technology.
