This project contributes to the Michigan-Ontario Ozone Source Experiment (MOOSE) field campaign scheduled to take place in the summers of 2021 and 2022 over metropolitan Detroit. MOOSE is a collaborative effort sponsored by the Michigan Department of Environment, Great Lakes, and Energy (EGLE), and includes participation from the Canadian government, NOAA, NASA, USEPA and the USFS. The goal of the campaign is to improve the understanding of the sources and chemistry associated with the production of ozone air pollution in the region.The research in this project supported by NSF includes the testing of hypotheses to better understand heterogeneous pathways to HONO formation and includes the measurement of stable isotopes that will serve as a unique tool to rigorously constrain sources, chemical processing pathways, and sinks of reactive nitrogen species based upon their respective isotopic signatures. This effort is expected to help to clarify the role of HONO in ozone production. The project includes improvements that will be made to the Community Multiscale Air Quality (CMAQ) chemical transport model that will benefit users of the model.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目为原定于2021年和2022年夏季在底特律大都会的夏季举行的密歇根州 - 户外臭氧源实验（Moose）田野运动做出了贡献。 Moose是密歇根州环境，大湖和能源部（EGLE）赞助的合作努力，包括加拿大政府，NOAA，NASA，NASA，USEPA，USEPA和USFS的参与。该运动的目的是提高对该地区臭氧空气污染相关的来源和化学的理解。NSF支持的该项目的研究包括对假设的测试，以更好地了解Hono组的异构途径，并包括稳定的同位素的测量将作为严格限制来源，化学加工途径和基于其各自的同位素特征的反应性氮种的水槽的独特工具。预计这项工作将有助于阐明Hono在臭氧生产中的作用。该项目包括将对社区多尺度空气质量（CMAQ）化学运输模型进行的改进，该模型将使该模型的用户受益。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛的评估来支持的。影响审查标准。
