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.

该奖项支持Joanne Romagni博士学位。亚利桑那州立大学托马斯·纳什（Thomas Nash）教授的学生，在德国美因兹（Mainz）的马克斯·普朗克化学研究所（Max Planck Chemittry for Distute）进行了十周的论文增强研究。她将与博士一起在生物地球化学系工作。 Franz Meixner和Juergen Kesselmeier及其研究小组成员。她的研究访问的具体目标是学习测量痕量氮气，通过痕量硫气体分析获得额外经验的方法，并构建和测试适合其对地衣和叶片研究的气体采样室。在她的研究中，这种经验将非常有用，以量化加利福尼亚州蓝橡木林地生态系统中的氮和硫痕量气体的来源和下沉。这些信息将提高我们对在气候变化中起作用的大气微量气体的生物源性的理解。 Max Planck化学研究所是世界上最受尊敬的研究机构之一，大气化学领域以及大气与生物圈之间的相互作用。罗马尼女士将与之一起工作的科学家是痕量气通量和氮和硫的全球生物地球化学循环的专家。他们开发了新的，有效的微气象方法，以监测植被和土壤中的氮气和硫气。获得这些技术的经验将直接受益于Romagni女士对林地生态系统中微量气体通量的博士学位论文研究。
