研究方向概述：

近年來，由於一系列減排措施的推行，我國主要城市群大氣細顆粒物（PM2.5）污染得到一定程度的改善。然而，臭氧污染日益嚴重，引起政府和公眾的廣泛關注。國外的相關經驗表明，臭氧治理比PM2.5要困難的多，需要時間也長的多。我國現階段普遍採取的以PM2.5為導向的控制策略不能滿足臭氧控制的需求，在PM2.5達標后，我國主要城市群的大氣污染控制勢必轉移到以臭氧為防控重點上來。以長三角、珠三角等典型光化學活躍區近地面臭氧污染為研究核心，在反應性有機物排放特徵、臭氧非線性變化控制機制以及氣候變化背景下大氣氧化性演變對近地面臭氧污染影響等方向開展深入研究，具體為：

1. 大氣反應性有機物來源量化與校驗：

反應性有機物在大氣化學過程和臭氧生成中起至關重要的作用，但其排放特徵和化學轉化尚未得到充分研究。針對當前反應性有機物來源研究的兩個薄弱環節：活性組分測量和化學轉化過程校正，藉助源排放測量、排放模型和文獻調研等手段，完善長三角和珠三角地區反應性有機物重要排放源化學成分譜，特別是補充現有反應性有機物源譜中缺失的支鏈烯烴、反應性醛類等關鍵活性組分，構建本地化的反應性有機物排放源資料庫；以2016年為基準年，構建中國東部地區高時空解析度的反應性有機物排放源清單；針對反應性有機物重要排放源，量化表徵大氣中反應性有機物從源到受體點的化學轉化過程，建立基於地面觀測、模型反演和衛星遙感的反應性組分來源校驗方法；並預估長三角和珠三角地區反應性有機物未來5~10年的排放趨勢。

2. 光化學活躍區臭氧非線性變化控制機制研究：

通過結合基於觀測模型、三維空氣質量模型和衛星遙感等三種技術手段，定量識別不同氣象條件下本地生成及區域傳輸對長三角和珠三角不同地區臭氧的相對貢獻，闡明不同地區臭氧及其前體物的非線性關係及其時空變化特徵，揭示不同氣象條件下VOC敏感、NOx敏感及過渡區的空間分佈；利用長期衛星遙感資料闡明長三角和珠三角地區評判VOC敏感、NOx敏感及過渡區的FNR標準，識別兩區域臭氧控制機制的長期變化趨勢，探索臭氧生成的敏感區域劃分隨NOx及VOCs削減的變化規律，為遏制臭氧污染事件發生的頻率和強度以及制定中長期臭氧達標規劃提供科學依據。

3. 氣候變化背景下大氣氧化性演變對近地面臭氧污染影響研究：

臭氧防控通常需要數十年的時間，在這一時間尺度上氣候變化對臭氧污染的影響不可忽視。根據長三角和珠三角多站點長期監測結果，建立描述臭氧、NOx及環境溫度關係的概念模型，識別溫度對不同區域臭氧生成效率的影響；將溫度因素納入排放源清單動態體系，在不同環境溫度下對部分揮發性VOCs排放源譜進行現場採樣與分析，闡明溫度對揮發性VOCs排放特徵的影響；在本地化的三維空氣質量模型中應用納入溫度因素的動態排放源清單並對環境溫度進行擾動，揭示兩區域的臭氧氣候補償效應，建立溫度與臭氧前體物響應關係之間的函數關係，為不同氣候變化背景下兩區域制定臭氧控制策略提供科學依據。
