3. 讨论交流

三、讲座内容

全球范围内，港口及其周边相关产业是温室气体和空气污染的重要来源。本文讨论了一个港口甲烷监测系统（Port-MMS）的原型，旨在为政策制定、监测以及减排策略效果评估提供支持，重点关注西半球最大的长滩港和洛杉矶港及其周边重工业。2019年至2025年间，SISTER（即“车载响应式标准仪器套件”）开展了10次移动空气质量实验室调查，该平台连续测量气象参数、气溶胶、包括甲烷（CH₄）在内的15种痕量气体，并采集目标空气样本以供实验室分析多达87种痕量气体。港口区域甲烷排放量为每年7.3±0.7 Gg，主要来自石油生产（71%）和炼油厂（25%）。实测（自上而下）的炼油厂甲烷排放量是加州空气资源委员会（CARB）自下而上估算值的三倍。通过超采样TROPOMI卫星数据，可推导出设施尺度（亚公里级）的排放量，其结果与现场实测数据的一致性优于与CARB数据的一致性。卫星异常相对强度与CARB清单之间的差异被认为是由瞬时释放造成的，这些释放事件在卫星甲烷分布图中的上十分位数值中有所体现，但可能未被纳入排放清单。该港口甲烷监测系统已在一次利益相关方研讨会上进行了展示，调查结果显示与会者对其多个应用领域表现出了很高的关注度。

四、报告人简介

Ira Leifer

Dr. Ira Leifer is a researcher at the Department of Chemical Engineering and the Marine Sciences Institute at University of California, Santa Barbara. He has worked for several decades on natural and unnatural hydrocarbons in the ocean and atmosphere by in situ and remote sensing, including oil, greenhouse gases, and other trace gases. Dr. Leifer has developed unique, state-of-the-art science platforms, such as SISTERTM – a mobile air quality laboratory for installation in a pickup truck and SeaSpiresTM – an oil slick thickness remote sensing package for airborne deployment. These and other custom developed science systems have been featured in numerous peer reviewed publications and major media.

Dr. Leifer is also the CEO and Chief Scientist of Bubbleology Research International (BRI), a small, flexible, greentech company focused on environmental consulting, instrumentation development, satellite data analysis and validation, and environmental assessment since 2003. BRI has handled complex projects for Fortune 500 companies, involving universities, the Navy, NASA, NSF, and other state and federal agencies.

Dr. Leifer received his Bachelor’s degree in physics/astronomy from SUNY at Stony Brook, New York, Master’s degree in aeronomy from University of Michigan, and Ph.D. in atmospheric sciences from Georgia Institute of Technology.

His active research areas and interests:

· Leak detection from oil and gas production, refining, and distribution

· Oil spill remote sensing

· Natural marine hydrocarbon seepage, relationship to reservoir dynamics, and production and upper food web ecosystem impacts.

· Health impacts of air pollution on downwind communities.

· Sustainable dairies and shrinking the environmental footprint in situ and remote sensing measurement of dairy methane, ammonia, aerosols, and other gas emissions to identify sustainable best practices.

· Rift valley volcanic trace gas emissions

· Arctic methane
