项目摘要

The air quality monitoring instrumentation to be purchased as part of this Research Tools and Instruments grant will support several components of Dr. Robert Gordon's and Dr. Claudia Wagner-Riddle's air quality research programs. The research programs that this equipment will support are focused on developing air quality management strategies that will ensure the sustainability of the agricultural industry and protection of the environment. The requested equipment includes a tunable gas analyzer (TGA) for nitrous oxide and selected components for using the TGA as part of an eddy covariance system for surface flux measurements. The TGA measures trace gas concentrations in an air sample using tunable diode laser absorption spectroscopy. It is a rugged, portable instrument designed for use in the field. Dr. Gordon and Wagner-Riddle will use this instrumentation as part of several on-farm and year-round greenhosue gas monitoring studies. Nitrous oxide is a potent greenhouse gas emitted by agro-ecosystems, and there is much potential for reduction of these emissions through mitigation practices tailored to the agricultural sector. The requested instrument is essential for the successful achievement of research goals in Dr. Gordon's and Wagner-Riddle's research programs. This

作为研究工具和仪器赠款的一部分，将购买的空气质量监测仪器将支持罗伯特·戈登博士和克劳迪娅·瓦格纳-里德尔博士的空气质量研究计划的几个组成部分。该设备将支持的研究计划侧重于制定空气质量管理战略，以确保农业的可持续性和环境保护。所要求的设备包括一个用于一氧化二氮的可调气体分析仪和使用该分析仪作为表面通量测量涡流协方差系统一部分的选定部件。TGA使用可调谐二极管激光吸收光谱法测量空气样品中的痕量气体浓度。这是一款坚固耐用的便携式仪器，专为现场使用而设计。戈登博士和瓦格纳里德尔将使用这种仪器作为几个农场和全年温室气体监测研究的一部分。一氧化二氮是农业生态系统排放的一种强有力的温室气体，通过针对农业部门的缓解做法，减少这些排放量的潜力很大。所要求的仪器是成功实现戈登博士和瓦格纳-里德尔研究计划的研究目标所必需的。这
