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.

该项目涉及在美国西北部选定地点长期测量半挥发性有机化合物（SOC），包括一个对自由对流层进行常规采样的地点。 该项目的目标包括使用SOC分子示踪数据更全面地描述亚洲排放物跨越太平洋的远距离迁移，并调查高纬度和高海拔地区的原始生态系统是否受到人为SOC沉积的影响。解决了目前缺乏可作为洲际大气迁移示踪剂的这类半连续数据的问题。 亚洲排放对有机污染物洲际运输和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，并为多达五名本科生提供研究经验。 该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NSF授予这位新开始的女教员的第一个奖项。
