臺灣空氣品質變異分析及衛星遙測資訊應用

中文摘要 亞洲大氣污染物之排放隨工業化與經濟快速發展而顯著成長,區域大氣污染物 (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。對於如何釐清與掌握這些境外貢獻,實有迫切需要。再者,若能進一步透過科學方法 (統計、模式模擬等) 檢視、掌握這些變因,不僅可以審慎評估空污政策之效益,亦可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,並且達到預警效果,使大眾能有所警覺而自我防護,公部門亦能提早因應。此外,衛星遙測技術可應用於區域或局部大氣污染之時空變化,例如沙塵及中國霧霾之監測,或是本地小尺度 露天燃燒之掌握。近期火災引發之空污緊急事件頻發,如何即時掌握其煙流之傳送與擴散,以及可能影響範圍,亦為重要之應變課題。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。

Variability Analysis of Air Quality and Advanced Application of Remote Sensing in Taiwan

英文摘要 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. There is an urgent need to clarify and grasp these extraterritorial contributions from long-range transport. Furthermore, if it is able to further examine and grasp these variables through scientific approaches (statistics, model simulations, etc.), we can not only carefully evaluate the effectiveness of air pollution control policies, but also further grasp and predict the changes of the short-term and mid-term regional atmospheric pollutants and the impact on air quality in Taiwan, and achieve an early warning. The public can be alert and protect themselves, and the relevant government departments can also respond early. In addition, satellite remote sensing technology can be applied to regional or local spatial and temporal changes in atmospheric pollution, such as the monitoring of dust and Chinese haze, or the mastering of small-scale local open burning. The recent fire-induced air pollution emergencies happened frequently, and it is important to grasp the transmission and dispersion of the smoke plume and its possible impacted area. Besides, the project also actively extends and participates in international collaboration and is in line with the current international technology.
