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 rural water and air quality research program. The requested equipment includes a tunable gas analyzer (TGA) for nitrous oxide and selected components for using the TGA as part of a eddy covariance system for surface flux measurements. The TGA measures trace gas concentration in an air sample using tunable diode laser absorption spectroscopy. It is a rugged, portable instrument designed for use in the field. Common applications include gradient or eddy covariance flux measurements. The TGA has allows for  in situ measurements of nitrous oxide. Dr. Gordon will use will this instrumentation as part of  several on-farm air quality studies. This instrumentation will immediately contribute to the training of a number of graduate students with several additional highly qualified personnel provided access over the next 5 years. 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.

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·戈登博士农村水和空气质量研究计划的几个组成部分。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。常见的应用包括梯度或涡流相关通量测量。TGA允许对氧化亚氮进行原位测量。戈登博士将使用这种仪器作为农场空气质量研究的一部分。这种仪器将立即有助于培训一些研究生，并在未来5年内为另外几名高素质人员提供机会。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。
