项目摘要

Climate in the Arctic is changing at a rapid pace. When vegetation reacts to these changes, chemicals called biogenic volatile organic compounds (BVOCs) can be released into the atmosphere. This project seeks to investigate how climate change affects the quantity and type of BVOCs released into the atmosphere and the chemical reactions these BVOCs undergo in the Arctic atmosphere. The investigators will accomplish their project goals through fieldwork on the North Slope of Alaska (NSA), collection and laboratory analysis of emission and atmospheric samples, and modeling of potential emissions and chemistry. For this project to have broad impacts, we will engage with students at Iḷisaġvik College (Alaska’s only tribal college), Baylor University and minority-serving University of California-Irvine and University of California-Riverside, local K-12 schools, and the broader scientific community. This is an integrated field experiment and modeling project focused on quantifying biogenic emissions from tundra vegetation and subsequent organic aerosol production. The project activities include targeted field campaigns across the North Slope of Alaska, laboratory analysis, and modeling. Specifically, the project intends to (1) Measure the release of volatile organic compounds by vegetation (biogenic VOC) under different environmental conditions (2) Model summer chemistry of BVOCs and (3) Measure the concentrations of BVOCs and their secondary organic aerosol products during field campaigns on the North Slope of Alaska. This work will culminate in (4) building a predictive understanding of how vegetation type and seasonal and climate variations across the North Slope of Alaska controls BVOC emissions and subsequent aerosol formation. By quantifying the relationships among physical and biological drivers for current vegetation emissions, this project will significantly advance predictions of the impacts of changing climate and vegetation on future vegetation emissions and organic aerosol composition and concentrations. Finally, this research will have broader impacts through: (1) Engaging with students at Iḷisaġvik College; (2) Training students at Baylor and minority-serving University of California-Irvine and University of California-Riverside; (3) K-12 outreach in local schools at UCI; and (4) Promoting transdisciplinary discussion of the impacts of changes in Arctic vegetation emissions on the atmosphere with a scientific workshop.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.
北极气候正在快速变化。当植被对这些变化反应时,可以将称为生物挥发性有机化合物(BVOC)的化学物质释放到大气中。该项目旨在研究气候变化如何影响释放到大气中的BVOC的数量和类型,以及这些BVOC在北极大气中经历的化学反应。研究人员将通过阿拉斯加北坡(NSA)的现场工作来实现其项目目标,对排放和大气样本的收集和实验室分析以及潜在排放和化学的建模。为了产生广泛影响的项目,我们将与IḷISAġVIK学院(阿拉斯加唯一的部落学院),贝勒大学和加利福尼亚大学 - 艾尔文大学和加利福尼亚大学河畔大学,本地K-11学校,本地K-11学校以及更广泛的科学界的学生互动。这是一个集成的现场实验和建模项目,旨在量化苔原蔬菜的生物发射以及随后的有机气溶胶生产。项目活动包括阿拉斯加北坡的有针对性现场活动,实验室分析和建模。具体而言,该项目打算(1)在不同的环境条件下测量植被(生物源)在不同的环境条件下释放挥发性有机化合物(2)BVOC的夏季化学模型,以及(3)测量BVOC及其二次有机气溶胶的浓度及其在阿拉斯加北部Slope of Alaska的田间活动期间。这项工作将在(4)建立对植被类型以及阿拉斯加北坡度的季节性和气候变化如何控制BVOC排放以及随后的气溶胶形成的预测性理解。通过量化现有植被排放的物理和生物学驱动因素之间的关系,该项目将大大提高气候和植被对未来植被排放以及有机气溶胶组成和浓度的影响的预测。最后,这项研究将通过:(1)与IḷISAġVIK学院的学生互动; (2)贝勒和加利福尼亚大学少数民族服务的学生和加利福尼亚大学 - 河畔大学的培训学生; (3)UCI当地学校的K-12宣传; (4)通过科学研讨会促进跨学科讨论北极植被排放对大气的影响的影响。该奖项反映了NSF的法定任务,并被认为是通过基金会的智力优点和更广泛的影响来通过评估来获得支持的支持。
