Asian Aerosol Source Identification, Chemical Transformation and Long Range Transport, Spring and Summer, 2001

该项目支持亚洲气溶胶特征实验的一个组成部分。该项目与亚洲科学家合作，在太平洋沿岸沿着建立了一个地面气溶胶测量网络，包括菲律宾、台湾、韩国、中国、日本和夏威夷的站点。其中几个网站已经建立，其他网站将增加ACE亚洲。气溶胶将通过便携式、连续采样、定径撞击器收集，所收集样本的子集将在以后根据气象和其他数据进行分析。分析技术包括总质量、同步加速器XRF痕量金属、烟尘和有机物测量以及离子色谱法。这些数据将提供资料的大小和化学成分的气溶胶在边界层和低对流层在东亚的大规模传输到北太平洋的时间。将获得关于来源和迁移途径的资料。将进行米氏计算，以评估这些气溶胶的辐射影响。

This project supports a component of ACE-Asia (Aerosol Characterization Experiment). The project contributes a ground-based aerosol measurement network along the Pacific Rim, including sites in the Philippines, Taiwan, Korea, China, Japan, and Hawaii in collaboration with Asian scientists. Several of these sites have been already established, and others will be added for ACE-Asia. Aerosols will be collected on portable, continuously sampling, sizing impactors and subsets of the collected samples will be later analyzed based on meteorological and other data. The analysis techniques include total mass, trace metals by synchrotron XRF, measurements of soot and organic matter, and ion chromatography. These data will provide information on the size and chemical composition aerosols in the boundary layer and lower troposphere in East Asia during a time of massive transport into the North Pacific. Information on sources and transport pathways will be obtained. Mie calculations will be performed to evaluate the radiative impact of these aerosols.
