CAREER: New Molecular Markers of Asian Air Emissions - Anthropogenic Semi-Volatile Organic Compounds

该项目包括对美国西北部选定地点的半挥发性有机化合物(SOC)进行长期测量，其中包括一个对自由对流层进行常规采样的地点。该项目的目标包括利用有机碳分子示踪剂数据更全面地描述亚洲排放跨越太平洋的远距离输送，并调查高纬度和高海拔的原始生态系统是否受到人为有机碳沉积的影响。将使用各种分析技术来确定所采集的大量环境样本的特征和来源，以解决这类可用作洲际大气运输示踪剂的半连续数据中目前存在的空白。亚洲排放对洲际运输和有机污染物全球循环的重要性是及时和重要的，其结果可能具有政策相关性。该项目将为两名研究生提供专业培训，并为最多五名本科生提供研究经验。这一职业奖的教育部分涉及对K-12学生及其教师的教育推广，包括那些来自代表性不足的族裔群体的学生。这个项目是美国国家科学基金会向这位新起步的女性教职员工颁发的第一个奖项。

This project involves long-term measurements of semi-volatile organic compounds (SOC) at selected locations in the U.S. Northwest, including a site routinely sampling the free troposphere. The objectives of this project include using SOC molecular tracer data to more completely characterize long-range transport of emissions from Asia across the Pacific Ocean, and investigating whether pristine ecosystems at high latitudes and elevations are affected by deposition of anthropogenic SOC. A variety of analytical techniques will be used to identify the characteristics and origin of the hi-volume ambient samples acquired, addressing a current void in semi-continuous data of this type available as tracers of intercontinental atmospheric transport. The importance of Asian emissions on intercontinental transport and global cycling of organic pollutants is timely and important, and results are likely to have policy relevance. The project will provide professional training for two graduate students and research experience for up to five undergraduates. The educational component of this CAREER award involves educational outreach to K-12 students and their teachers, including those from underrepresented ethnic groups. This project is the first NSF award to this new-start female faculty member.
