MRI: Acquisition of an Integrated Atmospheric Chemistry Mobile Laboratory

将获得一辆装有一套大气气溶胶实地研究仪器的移动拖车。这个移动实验室将允许同时测量气相物种，颗粒相化学和物理性质，以及边界层动力学在气溶胶研究的综合方法。主要的研究仪器包括测量气溶胶和云层垂直剖面的气溶胶激光雷达、测量颗粒大小分布的扫描迁移率粒度仪、用于收集和化学分析水溶性离子成分的液体粒子采样器/离子色谱仪，以及用于定量臭氧和气溶胶气相前体的气相色谱仪/质谱仪。还将包括测量关键化学物质（臭氧、一氧化碳、活性氮和二氧化硫）的配套仪器和一个基本气象站。流动实验室将用于实地实验，研究前体气体、它们的化学转变及其对大气氧化剂和气溶胶的影响之间的关系。这些测量解决了与全球气候变化、生物圈与大气之间的反馈机制、区域大气化学以及人为排放和光产物沉积对生态系统健康的影响有关的问题。流动实验室将为华盛顿州立大学的实地研究项目提供关键的基础设施，并与其他有关生物、城市和农业排放影响的机构合作。所得数据将支持对大气动力学和化学的详细描述，以便与氧化剂和颗粒物质的化学传输模型进行比较。该实验室将用于本科生和研究生的教育和培训，也应有助于招生。

A mobile trailer with a suite of instruments for field research on atmospheric aerosols will be acquired. This mobile laboratory will allow simultaneous measurements of gas phase species, particulate phase chemical and physical properties, and boundary layer dynamics in an integrated approach for aerosol studies. The major research instruments to be acquired are an aerosol LIDAR to measure vertical profiles of aerosols and clouds, a Scanning Mobility Particle Sizer to measure particle size distributions, a Particle in Liquid Sampler/Ion Chromatograph for collection and chemical analysis of water-soluble ionic components, and a Gas Chromatograph/Mass Spectrometer for the quantification of gas phase precursors of ozone and aerosols. Supporting instruments to measure key chemical species (ozone, carbon monoxide, reactive nitrogen, and sulfur dioxide) and a basic weather station will also be included. The mobile laboratory will be used in field experiments to study the relationship between precursor gases, their chemical transformations, and the resulting impacts on atmospheric oxidants and aerosols. These measurements address questions relevant to global climate change, feedback mechanisms between the biosphere and atmosphere, regional atmospheric chemistry, and impacts of the deposition of anthropogenic emissions and photoproducts on ecosystem health. The mobile laboratory will provide critical infrastructure for field research projects at Washington State University and in collaboration with others related to the impact of biogenic, urban, and agricultural emissions. The resulting data will support a detailed description of atmospheric dynamics and chemistry for comparison with chemical transport models of oxidants and particulate matter. The laboratory will be used for the education and training of undergraduate and graduate students, and should also help with student recruitment.
