This SGER (Small Grant for Exploratory Research) project involves airborne measurements of aerosol phase organic compounds during ACE-Asia (Aerosol Characterization Experiment-Asia). In this collaboration with Dr. Barry Huebert of the University of Hawaii, the PI is providing his aerosol sampling system for use in the NSF C-130 aircraft. In this particular configuration, the airflow will be passed through a particle concentrator, a diffusion denuder, and filters. This minimizes potential artifacts associated with the collection of semi-volatile organic compounds. Recent measurements have pointed to the potentially large and yet insufficiently well understood role of organic compounds in atmospheric aerosols and their climate forcing. The airborne measurement of organic carbon is a crucial component of the ACE-experiment which takes place in a region where the role of carbonaceous material is expected to be very significant.

该SGER（探索性研究小额赠款）项目涉及在ACE-亚洲（气溶胶表征实验-亚洲）期间对气溶胶相有机化合物的空中测量。在与夏威夷大学的巴里休伯特博士的合作中，PI提供了他的气溶胶采样系统，用于NSF C-130飞机。在该特定配置中，气流将通过颗粒浓缩器、扩散扩散器和过滤器。这最大限度地减少了与半挥发性有机化合物的收集相关的潜在人为因素。最近的测量表明，有机化合物在大气气溶胶及其气候强迫中的作用可能很大，但尚未得到充分的了解。有机碳的空中测量是ACE实验的一个关键组成部分，该实验在一个含碳物质的作用预计将非常重要的区域进行。
