This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This collaborative investigation into the forest atmosphere photochemistry will apply a unique set of collaborative approaches, focused on the chemistry occurring in the near-canopy environment. It is now well known that forests emit biogenic volatile organic compounds (BVOCs) that impact the physical (e.g. aerosols) and chemical (e.g. ozone) composition of the overlying atmosphere, and that this in turn impacts forest productivity. However, recent measurements of hydrogen oxide (HOx) radicals in forested areas differ significantly from model predictions, bringing into question understanding of the chemistry of BVOCs and their contribution to the chemistry of ozone and secondary aerosol formation. An intensive field campaign at the University of Michigan Biological Station (UMBS) during the summer of 2009 will take advantage of both the PROPHET (Program for Research on Oxidants: PHotochemistry, Emissions and Transport) and the FASET (Forest Accelerated Succession ExperimenT) facilities, experience and human resources. UMBS represents the ideal research community asset to enable pursuit of a better understanding of the complex atmospheric chemistry impacted by BVOCs and, additionally, to observe how that chemistry may change in the context of changing forest composition and climate. A combination of HOx, BVOC, aerosol, and oxidation product measurements will be made using a wide array of sophisticated instrumental techniques, taking advantage of our infrastructure for probing the vertical dimension (towers, a canopy access vehicle, aerosol LIDAR, and an instrumented aircraft). These measurements will then inform a modeling effort aimed at testing current understanding. It is anticipated that 12 graduate students and at least as many undergraduate research assistants will participate in the field campaign. During the study frequent data meetings will be held in which students will present and discuss the scientific implications of preliminary data. There will be many opportunities for atmospheric scientists to interface and collaborate with the entire UMBS community. A science symposium at UMBS that will include the forest ecology and biogeochemistry researchers who have interest in atmosphere-forest interactions will be organized.

该奖项是根据2009年的《美国复苏与再投资法》（公法111-5）资助的。该对森林氛围光化学的合作调查将采用一系列独特的协作方法，重点介绍了在近乎镜头环境中发生的化学反应。 现在众所周知，森林会散发出影响上覆氛围的物理（例如气溶胶）和化学（例如臭氧）组成的生物挥发性有机化合物（BVOC），这又影响了森林的生产率。 然而，森林区域中氧化物（HOX）自由基的最新测量与模型预测有很大差异，这使人们对BVOC的化学及其对臭氧化学和二次气溶胶形成的贡献感到疑问。 2009年夏季，密歇根大学生物站（UMB）进行的强化现场活动将利用先知（氧化剂研究计划：光化学，排放和运输计划）和Faset（森林加速继承实验）的设施，经验和人力资源。 UMB代表了理想的研究社区资产，可以更好地了解受BVOC影响的复杂大气化学反应，并观察到在改变森林组成和气候的情况下，化学反应如何改变。 HOX，BVOC，气溶胶和氧化产品测量的组合将使用多种复杂的仪器技术进行，利用我们的基础设施来探测垂直尺寸（塔，顶棚通道，气溶胶，气溶胶liDar和仪表飞机）。 然后，这些测量将为旨在测试当前理解的建模工作提供信息。 可以预计，至少有12名研究生和至少许多本科研究助理将参加现场运动。 在研究期间，将举行频繁的数据会议，学生将展示并讨论初步数据的科学含义。 大气科学家将有很多机会与整个UMB社区进行互动和合作。 UMB的科学研讨会将包括对大气 - 森林相互作用感兴趣的森林生态学和生物地球化学研究人员。
