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)

该项目涉及ACE-亚洲（气溶胶表征实验-亚洲）密集现场计划期间收集的有机气溶胶的化学表征。 ACE-亚洲是一个多研究者的国际计划，旨在表征东亚外流气溶胶的化学特性和辐射效应。 将在实地方案期间收集的样品中分析特定的有机示踪剂。 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，纤维素等分析技术是基于提取和GC/MS（气相色谱/质谱）。 这些信息将与相关数据一起沿着用于推断气溶胶源和源区。 将在韩国高山和亚洲其他可能的地面站点采集样本，并与Huebert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采集样本。
