项目摘要

This award supports Joanne Romagni, a Ph.D. student of Professor Thomas Nash at Arizona State University, for a ten week period of dissertation enhancement research at the Max Planck Institute for Chemistry in Mainz, Germany. She will work in the Department of Biogeochemistry with Drs. Franz Meixner and Juergen Kesselmeier and members of their research groups. The specific objectives of her research visit are to learn methodologies to measure trace nitrogen gases, to gain additional experience with trace sulfur gas analyses, and to construct and test gas sampling chambers appropriate for her research on lichens and leaves. This experience will be very useful in her research to quantify sources and sinks of nitrogen and sulfur trace gases in a blue oak woodland ecosystem in California. Such information will improve our understanding of the biogenic origins of atmospheric trace gases which play a role in climate change. The Max Planck Institute for Chemistry is one of the most respected research institutes in the world in the area of atmospheric chemistry and the interactions between the atmosphere and the biosphere. The scientists with whom Ms. Romagni will work are experts in the study of trace gas fluxes and global biogeochemical cycling of nitrogen and sulfur. They have developed new and efficient micrometeorological methods to monitor trace nitrogen and sulfur gases in vegetation and soils. Gaining experience with these techniques will directly benefit Ms. Romagni's doctoral dissertation research on trace gas fluxes in a woodland ecosystem.

这个奖项支持乔安妮罗马尼，博士。美国亚利桑那州州立大学教授托马斯纳什的学生，在德国美因茨的马克斯普朗克化学研究所进行为期十周的论文强化研究。她将与Franz Meixner和Juergen Kesselmeier博士及其研究小组成员在生物地球化学系工作。她的研究访问的具体目标是学习方法来测量微量氮气，获得额外的经验与微量硫气体分析，并构建和测试气体采样室适合她的地衣和树叶的研究。这一经验将是非常有用的，在她的研究，以量化源和汇的氮和硫的痕量气体在蓝橡树林地生态系统在加州。这些信息将提高我们对在气候变化中发挥作用的大气痕量气体的生物来源的理解。马克斯·普朗克化学研究所是世界上在大气化学和大气与生物圈之间相互作用领域最受尊敬的研究机构之一。与Romagni女士一起工作的科学家是研究痕量气体通量和氮和硫的全球地球化学循环的专家。他们开发了新的有效的微气象方法来监测植被和土壤中的痕量氮和硫气体。获得这些技术的经验将直接有利于Romagni女士关于林地生态系统中痕量气体通量的博士论文研究。
