This project consists of several activities aimed at improving our understanding of tropospheric aerosol chemistry. The first activity is a continuation of the long-term Mauna Loa aerosol chemistry record. This record includes aerosol nitrate/nitric acid, sulfate, methanesulfonate, magnesium, and calcium. The second activity involves the design and field testing of airborne aerosol samplers. This involves the testing of a total aerosol sampler (TAS) and the fabrication and testing of an impactor coupled to a porous diffuser, low turbulence inlet. The third activity involves the planning and coordination of a major field experiment (ACE-Asia) directed at studying the composition and physical properties of aerosols in the outflow from eastern Asia, and their transformations during transport over the Pacific ocean.

该项目包括几项旨在提高我们对对流层气溶胶化学的理解的活动。 第一个活动是延续长期Mauna LOA气溶胶化学记录。 该记录包括硝酸气溶胶/硝酸，硫酸盐，甲磺酸盐，镁和钙。 第二个活动涉及空气气溶胶采样器的设计和现场测试。 这涉及对总气溶胶采样器（TAS）的测试以及耦合到多孔扩散器低湍流入口的撞击器的制造和测试。 第三个活动涉及旨在研究东亚流出中气溶胶的组成和物理特性的主要田间实验（ACE-ASIA）的计划和协调，以及在太平洋上运输过程中的转化。
