This collaborative research project with Lynn Russell, Princeton University, is an investigation of the role of organic species in atmospheric particles. Measurements of aerosol organics in east Asian outflow will be made from shipboard (NOAA R/V Brown) and aircraft (NCAR C-130), during the ACE-Asia field program. The measurements include: 1) semi-continuous elemental/organic carbon (EC/OC) analysis using a thermo-optical detection technique, and 2) time-integrated filter samples for analysis by Fourier Transform Infrared spectroscopy. The EC/OC measurements provide an important indicator for the role of combustion emissions in the air masses sampled. The FTIR organic analyses describe the mass of organic species and classify those species by functional group and solubility in solvents of different polarity. This provides information about the mass fraction of organic compounds that are water-soluble and contribute to enhanced water uptake by particles. The hydrophobic organic fraction that does not dissolve in the particulate aqueous phase will also be quantified.

这项与普林斯顿大学Lynn Russell的合作研究项目是对有机物种在大气颗粒中的作用的研究。 在ACE-ASIA野外计划期间，将通过船上（NOAA R/V Brown）和飞机（NCAR C-130）制成East Aian Full的气溶胶有机物的测量。 测量值包括：1）使用热光检测技术的半连续元素/有机碳（EC/OC）分析，以及2）时间集成过滤样品，以通过傅立叶变换红外光谱法分析。 EC/OC测量值为燃烧排放在被采样的空气质量中的作用提供了重要的指标。 FTIR有机分析描述了有机物种的质量，并按功能群和溶解度对不同极性的溶剂进行了分类。 这提供了有关水溶性的有机化合物的质量分数，并有助于颗粒增强的水吸收。 在颗粒相中不溶于颗粒相的疏水有机馏分也将被量化。
