    Abstract: 本計畫在整合型計畫群中所扮演的角色主要為研究亞洲污染物境外傳輸對台灣的影響,研究題目設定為模擬中國南方到中南半島這一大塊地區的氣膠-輻射-雲之交互作用,過去一年的研究工作主要在以下項目,並持續進行中:(一)測試WRF-CMAQv3.8.1 coupled model,(二)同時正與林唐煌教授合作,以其提供的MODIS產物,評估中南半島及中國南方地區的人為污染物排放量(三)以MODIS產物修正東南亞地區的landuse。模擬時間為2013年3-4月,東南亞生質燃燒期間。新年度將模擬2018年3-4月的觀測實驗,另外,由於中國塵霾問題在本年度引起國人關注,因此本研究配合整合型計畫,加強了在這方面的研究,並寫了兩篇文章,一篇文章是模擬2015年10月境外傳輸塵霾季節初期在台灣北端的氣象場及PM2.5特性,另一篇為設計一個經濟且簡單的方法去估算2006-2015年台灣西半部各地境外傳輸與當地污染的貢獻百分比。此外,在2017年11月29日及2017年12月23-24日發生台灣西半部大範圍PM2.5高濃度塵霾事件,經判斷主要為當地污染所造成,為釐清來自亞洲大氣污染物境外傳輸的貢獻,研究以當地污染為主、境外傳輸為次的個案也是有所必要,還有,造成這種在台灣西半部大範圍影響的原因為何,是否與台電火力發電機組增加有關,還是僅是氣象因素所造成,這些都蠻值得研究的。 ;This project is the only one that use air quality modeling to simulate the long-range transport of air pollutants from Asian continent. The topic of the present project is to simulate the aerosol-radiation-cloud interaction and met several problems. In the last year, we focus on the following items and will continue to complete them: First, testing the WRF-CMAQv3.8.1 coupled model. Second, cooperating with Prof. Tang-Huang Lin. We will apply the MODIS products provided by Prof. Lin and try to evaluate and modify the anthropogenic emission in the Southeast Asia. Third, using the MODIS product to modify the land use over the Southeast Asia. The simulation period is March to April in 2013, the biomass burning season. In the coming year, we will also simulate the 2018 biomass burning campaign.In addition, because the Chinese haze problems have attracted wild attention in Asia. We will help to study such issue for the integrated project. In the last year, we have written two manuscripts. One is to simulate the PM2.5 at the northern tip of Taiwan during early stage of haze season, October 2015. This manuscript has been accepted in AAQR. The other manuscript is to design a economic and efficient method to estimate the contribution of long-range transport and local pollution to PM2.5 in western Taiwan. This manuscript is still in review. Haze episodes occurred in the wide range of western Taiwan, e.g., on Nov 29 and Dec 23-24 in 2017. These haze episodes were judged to be caused by the local pollution. In order to clarify the contribution from the long-range transport, to study such haze episodes is necessary. We need to understand whether they were caused by the increase of thermal power units or just by meteorological factors.
