This project supports the deployment of instrumentation to study aerosol chemistry on the C-130 aircraft during ACE-Asia (Aerosol Characterization Experiment). A total aerosol sampler (TAS) will be used to collect aerosols without inlet losses and analyze them for major ions. A micro-orifice impactor will be used to collect size-segregated samples for ion analysis. Samples will be collected on a single stage impactor for analysis of EC/OC (organic/elemental carbon). Procedures for the analysis of these samples using a new EC/OC analyzer will be developed in time for the field deployment. An aerodynamical particle analyzer (APS) will be used to determine particle size distributions in the 0.5 - 10 micron range. In addition, PI Barry Huebert will serve as Lead Scientist for the ACE-Asia experiment.

该项目支持在ACE-亚洲（气溶胶特性实验）期间在C-130飞机上部署研究气溶胶化学的仪器。将使用总气溶胶采样器（TAS）收集气溶胶，而不会发生入口损失，并分析其主要离子。将使用微孔冲击器收集尺寸分离的样品进行离子分析。将在单级撞击采样器上采集样品，用于分析EC/OC（有机/元素碳）。将及时制定使用新的EC/OC分析仪分析这些样本的程序，以便进行实地部署。将使用空气动力学颗粒分析仪（APS）测定0.5 - 10微米范围内的粒度分布。此外，PI巴里休伯特将担任ACE亚洲实验的首席科学家。
