Source Apportionment of Asian Continental Aerosols and Their Associated Direct Climate Forcing Using Molecular Markers

本项目涉及在ACE-Asia（气溶胶表征实验-亚洲）密集实地项目中收集的有机气溶胶的化学特性。ACE-Asia是一个由多个研究者组成的国际项目，旨在表征东亚流出的气溶胶的化学性质和辐射效应。特定的有机示踪剂将在实地项目中收集的样品中进行分析。选择这些示踪剂来指示来源，如城市，石油，生物质燃烧，微生物，植物蜡，高等植物，木质素，纤维素等。分析技术以萃取和GC/MS（气相色谱/质谱）为基础。这些信息将与相关数据一起用于推断气溶胶的来源和来源区域。样本将在韩国高山以及可能在亚洲的其他地面地点收集，并与休伯特博士（夏威夷大学，ATM-0002698）合作，使用C-130飞机上的总气溶胶采样器收集。

This project involves the chemical characterization of organic aerosols collected during the ACE-Asia (Aerosol Characterization Experiment - Asia) intensive field program. ACE-Asia is a multi-investigator, international program designed to characterize the chemical properties and radiative effects of aerosols in the outflow from eastern Asia. Specific organic tracers will be analyzed in samples collected during the field program. These tracers are chosen to indicate sources such as urban, petroleum, biomass burning, microbial, plant waxes, higher plants, lignins, cellulose, etc. The analysis technique is based on extraction and GC/MS (gas chromatography/mass spectrometry). This information will be used, along with related data, to infer aerosol sources and source regions. Samples will be collected at Kosan, Korea, and possibly other ground sites in Asia, as well as with the Total Aerosol Sampler on the C-130 aircraft in collaboration with Dr. Huebert (University of Hawaii, ATM-0002698)
