104年度辦理雲林離島工業區基礎工業區(雲嘉南空品區)空氣品質評估模式探空數據資料計畫

中文摘要 本計畫主要目的為蒐集雲林離島工業區夏、冬兩季每季7 天之探空數據,並進行數據擷讀後處理,以建立雲林離島工業區(雲嘉南空品區)空氣品質評估模式探空數據資料。此外,本計畫亦將協助環保署辦理環境執法業務檢討會 及環境執法技術研討會,以提昇空氣污染物監督稽查之環境執法效能與相關業務人員對於空氣品質保護及空氣污染物總量查核之督察管制知能。根據本計畫已完成之探空觀測結果,經與中央氣象局板橋探空站、空軍氣象聯隊馬公、屏東探空站以及美國國家氣象局國家環境預測中心(NCEP) 再分析資料等高空氣象資料進行比對分析後顯示,在夏季觀測期間,各探空站垂直溫度剖面彼此間差異不大;而在冬季觀測期間,各站間的差異較夏季顯著。在冬季觀測期間,無論早上或晚上,板橋站之氣溫在各高度皆為最低,其餘各站則各有高低;平均後逆溫層之高度則以板橋站為最高,馬公站其次,屏東最低,本計畫(臺西站)之逆溫層高度則介於馬公及屏東之間。而在利用觀測結果進行空品模式所需混合層高度的估算部分,估算結果顯示,在日間部分,無論夏季或冬季,均以板橋探空觀測所估算的混合層最高,馬公站其次,屏東站最低,本計畫(臺西站)的估算結果則介於馬公與屏東之間。在夜間部分,夏季以板橋最高,冬季則以馬公最高。整體而言,夏季期間各站估算結果彼此間差距並不大,但冬季的差異較明顯(尤其日間)。 綜合上述分析,本區域若採用板橋站探空資料所估算的混合層高度會傾向高估,採用屏東站則會傾向低估,馬公站估算的混合層高度則與本計畫(臺西站)觀測估算結果較相近,相關性亦較佳。因此,就目前分析結果而言,若採 用馬公站長期探空資料搭配本計畫(臺西站)觀測數據調校後進行混合層高度估算,應可得到較近似當地的混合層高度估算結果。 本計畫試以離島工業區不同煙囪高度的排放源進行模擬測試,經以本計畫探空觀測資料所調校後的氣象資料以及傳統上以中央氣象局梧棲站搭配板橋探空站的氣象資料分別進行空品模式模擬,兩者模擬結果確實存在差異,惟並無一致性的偏差趨勢。

2015 Annual Yunlin Offshore Industrial Estate Park (Yun Jia Nan Air Quality District) Air quality model simulation radiosonde data project.

英文摘要 The main focus of this project, is to collect Radiosonde data for 7 days per season in the Yunlin Offshore Industrial Estate Park during Summer and Winter. Then processing it with data capture, to set up the Yunlin Offshore Industrial Estate Park (Yun Jia Nan Air Quality District) Air quality model simulation data plan. Moreover, this project also will be used in the Environmental law enforcement profession review conference and the Environmental law enforcement skill seminar. To improve the supervision and inspection of air pollutant, in order to enhance the efficiency and effectiveness of inspectors in air quality protection and ability in total air pollutant inspection. According to the already completed Radiosonde observations on this project, together with reanalysis of other high altitude meteorological data of the Banqiao of Central Weather Bureau , Magong and Pingtung of Air Force Weather Wing radiosonde station and the NCEP. It shows that during the summer observation period, there was little differences between the Vertical Temperature profiles of different sounding stations. However during the winter observation period compared to summer there was a significant amount of difference between the various sounding stations. In the Winter period regardless of day or night, the air temperature in Banqiao station was the lowest in all heights, whereas the other stations had high and lows. The averages of the height in the inversion layer Banqiao was the highest, Magong station being second with Pingtung station being the lowest. In this project (Taixi Station) the inversion layer height was between Magong and Pingtung. The results of the Radiosonde observation were used to carry out air quality simulations with a desired mixing layer height estimate. The estimate showed that during the day, whether in summer or winter, on average the radiosonde observation Banqiao had the highest mixed height layers, Magong second and Pingtung the lowest. In this project (Taixi Station) the mixed layer height was between Magong and Pingtung. During the night, in summer Banqiao was the highest with Magong being the highest in winter. Overall during the summer period each station results had little differences, however in the winter the differences quite noticeable (especially in the day). Combining the above analyses, If Yunlin region using the data from Banqiao station, then the estimated mixed layer height will likely be overestimated. If using the data from Pingtung station, then the estimated mixed layer height will likely be underestimated. Magong station data results of the mixed layer height, seems to have a higher correlation to the current project (Taixi station). Therefore basing on our previous analyses, if using Magong station long term radiosonde data for this project (Taixi station), adjusting with the radiosonde observation data then proceed with mixing layer height estimates, should be able to gain a closer result to the Yunlin mixed layer height estimates. This project used the different chimney height of emission sources from an Offshore Industrial Estate Park, to carry out a simulation test. Using the radiosonde observations according adjusted meteorological data and Central Weather Bureau Wuqi data coupled with the Banqiao sound station meteorological data to carry out an air quality model simulation. Comparing the two simulation tests, it can be seen that there is indeed a difference between the two simulations, with no consistent trends existing between the two.
