Measurements of Tropospheric Nitric Acid, Sulfur Dioxide, and Aerosols

该项目包括旨在提高我们对对流层气溶胶化学的理解的几项活动。 第一项活动是莫纳罗亚山长期气溶胶化学记录的延续。 该记录包括气溶胶硝酸盐/硝酸、硫酸盐、甲磺酸盐、镁和钙。 第二项活动涉及设计和实地测试空气悬浮微粒采样器。 这涉及到总气溶胶采样器（TAS）的测试和连接到多孔扩散器，低湍流入口的冲击器的制造和测试。 第三项活动涉及规划和协调一项大型实地实验（亚洲环境实验室），旨在研究从东亚流出的气溶胶的成分和物理特性及其在太平洋上空迁移过程中的变化。

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.
