區域大氣污染物 (例如，酸性污染物、沙塵、霾害、臭氧等) 之長程傳送於特定季節對臺灣空氣品質影響甚鉅。本計畫延續前期所建立之一套科學流程方法檢視、掌握境外貢獻這變因，以審慎評估空污政策之效益，並進一步掌握與預測短中期區域大氣污染物的變化及臺灣空氣品質的影響。對於境外傳輸對臺灣的影響之探討，著重以分析事件為主，藉此瞭解當事件日發生時境外傳輸對臺灣的衝擊以及傳輸機制，達到預警效果，提供公部門提早因應之參考資訊。本期計畫持續探討東亞區域長期氣候變異、短期天氣型態及污染物排放，定量東亞區域及臺灣地區大氣污染物背景濃度，並釐清境外大氣污染物貢獻量。另利用WRF/CMAQ數值模式建立區域大氣傳送模式系統，評估與預測境內外大氣污染物對臺灣之影響。進一步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。此外，亦積極拓展及參與國際交流並與國際技術接軌。

The long-range transport of regional atmospheric pollutants (eg, acidic contaminants, dust, haze, ozone, etc.) has a significant impact on Taiwan's air quality during certain seasons. Using the scientific methods established in the previous project, the current project continues to examine the impact of transboundary pollution, to carefully evaluate the benefits of air pollution control policies, and to further predict the changes in air pollutants in short- and medium-term as well as the corresponding impacts on air quality in Taiwan. The discussion on the impact of transboundary pollution in Taiwan will focus on analyzing specific events to understand the formation of the episode and the transmission mechanism so as to achieve early precaution measures and provide relevant information to the local authority for contingency plan. 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 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.
