This project will conduct comprehensive biogenic volatile organic compound (BVOC) emission measurements for an Arctic tundra ecosystem with the goals of understanding the impact of BVOC emissions on atmospheric chemistry and the effects of global change factors in the Arctic on BVOC emissions. The project has three experimental components which span spatial and temporal scales to achieve these goals. (1) A comprehensive species characterization campaign will identify Arctic plants that are important BVOC emitters. (2) An intensive field campaign will use micrometeorological techniques to measure isoprene and ozone fluxes above a tundra ecosystem near the Toolik Field Station in collaboration with an on-going project studying ecosystem carbon balance, and these data will be used with a photochemical model to study impacts on atmospheric chemistry. (3) Leaf-level and chamber enclosure measurements at existing global change factor manipulation sites will allow for predictions of how ecosystem BVOC emissions will change in the future.The project will bring two underrepresented minority students, one from the Central Valley in California and the other from urban Chicago, to the Toolik Field Station in Alaska for undergraduate research. The principal investigator has an on-going collaboration with the Peggy Notebaert Nature Museum of the Chicago Academy of Sciences to communicate global climate change themes to high school teachers, and he will incorporate the field experiences from this proposal into his teaching materials. In addition, results of the research will be communicated to the broader scientific community through publication in peer-reviewed journals and presentations at meetings where these cross-disciplinary research results can be shared.

该项目将对北极苔原生态系统进行全面的生物挥发性有机化合物（BVOC）排放测量，目的是了解BVOC排放对大气化学的影响以及北极全球变化因素对BVOC排放的影响。 该项目有三个实验部分，跨越空间和时间尺度来实现这些目标。 (1)一项全面的物种定性活动将确定北极植物是重要的BVOC排放者。 (2)一项密集的实地活动将利用微气象技术，与一个正在进行的研究生态系统碳平衡的项目合作，测量图里克野外站附近苔原生态系统上方的异戊二烯和臭氧通量，这些数据将与光化学模型一起用于研究对大气化学的影响。 (3)在现有的全球变化因素操纵网站的叶片水平和腔室外壳测量将允许如何生态系统BVOC排放量的预测将在future.The项目将带来两个代表性不足的少数民族学生，一个来自加州的中央谷和其他城市芝加哥，在阿拉斯加的图里克野外站进行本科生研究。 首席研究员与芝加哥科学院的Peggy Notebaert自然博物馆正在进行合作，向高中教师传达全球气候变化主题，他将把这项建议的实地经验纳入他的教材。 此外，研究结果将通过在同行评审的期刊上发表和在会议上发表演讲传达给更广泛的科学界，这些跨学科的研究结果可以共享。
