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

在自然和受污染的环境大气中形成有机气溶胶的过程很重要，但相对难以表征，而且仍然知之甚少。 根据主要研究仪器计划，科学和工程学院的跨学科小组将获得两种研究级仪器：质子转移质谱仪和气溶胶质谱仪，并将其用于合作项目，解决对大气化学和空气质量非常重要的研究问题。 将特别强调对环境大气气相有机化合物和细颗粒气溶胶的化学生产、增长、转化和归宿进行实验室和实地研究。 这项研究对气候，人类健康和公共政策具有广泛的影响。 该项目的其他更广泛的影响包括仪器技术和应用的进步，以及在项目调查人员的指导下为研究生和本科生提供尖端研究机会。

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.
