Fast-response analyzer for the determination of nitrous oxide flux and management practices to reduce emissions

作为研究工具和仪器拨款的一部分，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项目的几个组成部分。该设备将支持的研究项目侧重于制定空气质量管理策略，以确保农业的可持续性和环境保护。所要求的设备包括用于氧化亚氮的可调谐气体分析仪（TGA）和用于将TGA作为涡流相关系统的一部分用于表面通量测量的选定组件。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。它是一种坚固耐用的便携式仪器，专为野外使用而设计。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效温室气体，通过针对农业部门的缓解做法，减少这些排放的潜力很大。所要求的仪器对于成功实现戈登博士和瓦格纳-里德尔的研究项目的研究目标至关重要。这

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
