This project is an effort to use aerosol source apportionment to study the origin, transformations, and light scattering properties of aerosols in the outflow of Eastern Asia. This study will be carried out in the context of the ACE-Asia experiment. Aerosols will be collected for this study at Cheju Island, Korea and ground sites in China. The analyses will include a broad range of organic and inorganic compounds, and stable isotope ratios of important tracer elements. These analyses will involve ion chromatography, gas chromatography with mass spectrometric detection, and magnetic-sector, multi-collector inductively coupled plasma-mass spectrometry. This is a collaborative effort involving investigators from Georgia Institute of Technology, NCAR, and Oregon State University.

本项目致力于利用气溶胶源解析方法研究东亚地区外流气溶胶的来源、转化和光散射特性。这项研究将在ACE-Asia实验的背景下进行。将在韩国济州岛和中国的地面站点为这项研究收集气溶胶。分析将包括广泛的有机和无机化合物，以及重要示踪元素的稳定同位素比率。这些分析将涉及离子色谱、气相色谱和质谱学检测，以及磁扇区、多收集器电感耦合等离子体质谱。这是佐治亚理工学院、NCAR和俄勒冈州立大学的研究人员共同努力的结果。
