Source Apportionment of Asian Continental Aerosols and their Associated Direct Climate Forcing Using Molecular Markers and Isotope Signatures

本计画系利用气溶胶源解析法来研究东亚外流气溶胶的来源、变化及光散射特性。 这项研究将在ACE-亚洲实验范围内进行。 本研究将在韩国济州岛和中国地面研究中心采集气溶胶。 分析将包括各种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法、气相色谱质谱检测法和磁扇形、多收集器电感耦合等离子体质谱法。 这是一项合作努力，涉及来自格鲁吉亚理工学院，NCAR和俄勒冈州州立大学的调查人员。

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.
