研究方向
大氣污染（如灰霾、霧霾空氣）不僅會嚴重影響空氣品質和人體健康，同時也會影響城市、國家形象以及和鄰國的關係；而污染治理又需要大量的資金與技術。如何通過最小的治理成本達到最大的治理效果，制定出國內與國際、企業和百姓都滿意的環境政策，是一個涉及從大氣科學到地球系統科學、從經濟學到心理學等跨學科的複雜問題。本課題組的研究方向主要包括：大氣污染科學、地球系統科學和國際國內環境政策研究等
大氣污染科學：主要通過實驗觀測和多尺度大氣化學傳輸模型等手段研究大氣光化學反應機理、雲水化學反應機理、二次氣溶膠（如SOA、硫酸鹽、硝酸鹽等）的多相生成機制、以及氣溶膠的化學與物理演變過程等
地球系統科學：主要通過衛星遙感資料、全球地面觀測網和氣候模型等手段 分析研究大氣污染物與區域氣候及地表性質之間的作用關係（即污染物對區域氣候的影響，以及未來城市化、氣候改變等對空氣品質的影響），短壽命污染物（如臭氧，氣溶膠）、長壽命污染物(如二氧化碳）與生態系統碳循環三者之間的相互影響關係等
國際國內環境政策：利用空氣品質、污染治理、人口信息，農業產量和氣候變化等數據，結合健康暴露模型、投入產出模型、能源經濟均衡模型和不同政策分析理論，探討我國短期和中長期綜合治理大氣污染物和溫室氣體排放、酸沉降、氣候變化 以及與污染物跨境傳輸相關的國內國際環境政策
