Through this work the investigators will further develop and apply their global 3-D chemical transport model (IMPACT) to study tropospheric photochemistry and long-range transport. Model enhancements will include the chemistry of organic aromatic compounds, and organic peroxides produced from isoprene. The inclusion of selected reactive nitrogen tracers will enable investigation of long-range transport of reactive nitrogen, ozone and its precursors and the determination of ozone production efficiencies. Data from a variety of recent field campaigns will be compared with model simulation outputs. Results will likely bring about significant advancements in our present understanding of the photochemistry of some key oxidants, peroxides and organic nitrates on the global scale. The broader impacts of this project include providing new and potentially important information on global ozone production, and the effects of human activities on air quality and climate. This project will also contribute to the education and research experience of a graduate student at the University of Michigan.

通过这项工作，研究人员将进一步开发和应用他们的全球三维化学传输模型（IMPACT）来研究对流层光化学和远距离传输。 模型增强将包括有机芳香族化合物的化学，以及由异戊二烯产生的有机过氧化物。 列入选定的活性氮示踪剂将能够调查活性氮、臭氧及其前体的远距离迁移，并确定臭氧的产生效率。 将把最近各种实地活动的数据与模型模拟结果进行比较。 结果可能会带来显着的进步，在我们目前的理解的一些关键氧化剂，过氧化物和有机硝酸盐在全球范围内的光化学。 这一项目的更广泛影响包括提供关于全球臭氧生成以及人类活动对空气质量和气候的影响的新的和可能重要的信息。 该项目还将有助于密歇根大学研究生的教育和研究经验。
