Trace gas analyzer for N20 emissions from agricultural systems

作为这项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一氧化二氮的可调谐气体分析仪(TGA)和用于使用TGA作为用于表面通量测量的涡流协方差系统的部分的选定部件。TGA使用可调谐半导体激光吸收光谱测量空气样品中的痕量气体浓度。这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动协方差通量测量。TGA允许对一氧化二氮进行现场测量。戈登博士将使用这种仪器作为其几项农场空气质量研究的一部分。这一工具将立即有助于培训一些研究生，并在今后5年内提供更多的高素质人员。该设备将支持的研究计划侧重于制定空气质量管理战略，以确保农业行业的可持续性和环境保护。

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.
