This project seeks to develop methods for using existing and ongoing carbonyl sulfide (COS) observations to estimate carbon tracer gas exchange, including carbon dioxide (CO2) in order to better understand the effect of tree litter on carbon cycling within forests. This is an important step toward increasing our understanding of the carbon cycle, and the knowledge gained through the course of this project will enhance our ability to understand and project the impact of changes to the carbon cycle on climate change and the ecosystem. Additionally, the research team will work with a local high school teacher to develop a high school-level leaf litter sorting activity, which will provide students with hands-on experience related to real-world scientific research.The two specific aims of this work include: (1) to distinguish the influence of different components of forest ground cover on the trace gas exchange of COS; and (2) to integrate the importance of understory COS fluxes on ecosystem- and regional-scale evidence of plant functioning. This work seeks to include the collection of tower flux measurements, the processing of remote sensing and inventory data for these tower-scale measurements, Lagrangian inversions for COS surface fluxes, and the identification of previously unknown COS fluxes. This work also includes an 8-week visit from a local high school teacher to develop a litter-sorting activity, which will then be implemented at other nearby schools. Additionally, four local high school students will be invited for 6-week summer internships in the Rutgers Research Intensive Summer Experience (RISE) program.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.

该项目旨在开发使用现有和正在进行的羰基硫化物（COS）观察结果来估计碳示踪剂气体交换的方法，包括二氧化碳（CO2），以便更好地了解树垫对森林内碳循环的影响。这是迈向提高我们对碳循环的理解的重要一步，在该项目过程中获得的知识将增强我们理解和投射变化对碳循环对气候变化和生态系统的影响的能力。此外，研究团队将与当地的高中老师合作开发高中层的垃圾分类活动，这将为学生提供与现实科学研究有关的动手经验。这项工作的两个具体目标包括：（1）区分森林地面覆盖不同组成部分的影响cos of cos of cos of cos of cos; （2）整合了林下COS通量对植物功能的生态系统和区域规模的证据的重要性。这项工作旨在包括塔通量测量值的收集，这些塔式测量值的遥感和库存数据的处理，lagrangian cos表面通量的倒置以及以前未知的cos通量的识别。这项工作还包括一位当地高中老师进行为期8周的访问，以开发垃圾排序活动，然后在附近的其他学校实施。此外，将邀请四名当地高中学生参加Rutgers研究密集的夏季经验（RISE）计划的为期6周的暑期实习。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优点和更广泛影响的评估来评估的，因此被认为值得支持。
