This CAREER project will investigate how natural and human-caused interannual variability in the sources and sinks of reactive trace gases from forests influence air quality across North America. Observations and models will be combined to assess the role of interannual variability in the biosphere on atmospheric chemistry and air quality. This research has four objectives: (1) Characterize interannual variability in simulated biogenic reactive trace gas sources/sinks and their impacts on air quality in the US, driven by meteorology and phenology; (2) Develop time-varying land cover inputs that can be used to simulate the impacts of recent historical land use/land cover changes on atmospheric chemistry and air quality in the US.; (3) Determine how changing interactions between forests and atmospheric chemistry modify the impacts of concurrent changes in anthropogenic emissions on air quality in the US.; and (4) Identify and attribute important patterns in ground- and satellite-based observations of atmospheric chemical composition to spatiotemporal variability in the biosphere. The education and outreach plan is focused on expanding science data literacy in atmospheric chemistry.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.

该职业项目将调查自然和人为造成的际变异性如何在森林中反应性痕量气体的来源和下沉影响整个北美的空气质量。 观测和模型将合并，以评估生物圈中大气化学和空气质量的生物圈中变异性的作用。这项研究具有四个目标：（1）表征模拟生物反应性痕量气体/水槽中的年际变异性及其对美国空气质量的影响，在气象学和物候学的驱动下； （2）开发时间变化的土地覆盖投入，可用于模拟美国最近的历史土地使用/土地覆盖对大气化学和空气质量的变化的影响。 （3）确定森林与大气化学之间的变化如何改变了人为排放对美国空气质量的并发变化的影响。 （4）在基于地面和卫星的大气化学成分观察中确定和属性的重要模式，以使生物圈中的时空变异性变异。 教育和外展计划的重点是扩大大气化学的科学数据素养。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响标准，被认为值得通过评估来获得支持。
