Acquisition of Instrumentation for Measurement of Airborne Organics and Fine Particulate Matter

在自然和被污染的环境大气中导致有机气溶胶形成的过程是重要的，但相对难以表征，并且仍然知之甚少。在主要研究仪器计划下，科学与工程学院的一个跨学科小组将获得两台研究级仪器：质子传递质谱仪和气溶胶质谱仪，并将它们用于解决大气化学和空气质量高度重要的研究问题的合作项目中。将特别强调实验室和实地研究，以确定环境大气气相有机化合物和细颗粒气溶胶的化学生产、生长、转化和命运。这项研究对气候、人类健康和公共政策有着广泛的影响。该项目的其他更广泛的影响包括仪器技术和应用的进步，以及研究生和本科生在项目研究者指导下的前沿研究机会。

Processes resulting in the formation of organic aerosols in the natural and polluted ambient atmosphere are important yet relatively difficult to characterize and remain poorly understood. Under the Major Research Instrumentation Program an interdisciplinary group of Science and Engineering faculty will acquire two research grade instruments: a Proton Transfer Mass Spectrometer and an Aerosol Mass Spectrometer and use these in collaborative projects addressing research issues of high importance to atmospheric chemistry and air quality. Particular emphasis will be placed on laboratory and field studies characterizing the chemical production, growth, transformation and fate of ambient atmospheric gas-phase organic compounds and fine particulate aerosols. This research has broad implications for climate, human health and public policy. Additional broader impacts of the project include advancements in instrument technology and application and cutting-edge research opportunities for graduate and undergraduate students under the direction of the project investigators.
