SGER: Aerosol Characterization Experiments (ACE)-Asia 2001: Fine Particulate Organic Material in the Asian Aerosol

这个SGER(探索性研究小额赠款)项目涉及在ACE-ASIA(气溶胶特性实验--亚洲)期间对气溶胶相有机化合物进行的空中测量。在与夏威夷大学的Barry Huebert博士的合作中，PI正在提供他的气溶胶采样系统，用于NSF C-130飞机。在这种特殊结构中，气流将通过颗粒浓缩器、扩散疏散器和过滤器。这最大限度地减少了与收集半挥发性有机化合物相关的潜在伪影。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，但了解得还不够充分。空气中有机碳的测量是ACE实验的一个重要组成部分，该实验在一个碳质材料的作用预计非常重要的地区进行。

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.
