This project, part of the NSF Major Research Instrumentation Program, supports the acquisition of a new instrument at the University of Minnesota (UMN) - Twin Cities for making highly accurate measurements of organic compounds in the atmosphere. The instrument will be used both in the field and in the laboratory. Field sites where data will be collected include the UMN Tall Tower Observatory and the PROPHET tower at the University of Michigan Biological Station. Newly acquired data from the instrument will be used to improve scientific understanding of the biogeochemistry of organic carbon in the land-atmosphere system, with an emphasis on atmospheric composition, land-atmosphere coupling, and the processes driving air pollution and global change.The instrument, a Proton-Transfer-Reaction Time-Of-Flight Mass Spectrometer (PTR-TOF-MS), will be used to address important scientific issues including: (1) Land-atmosphere carbon exchange and volatile organic compounds (VOCs); (2) Chemical properties and aging of gas-phase organics; (3) Organic gas-aerosol interactions; and (4) Organic carbon biogeochemistry in soils. The instrument will also support the education of graduate and undergraduate students in Land and Atmospheric Science (LAAS) Program at the University of Minnesota.

该项目是NSF主要研究仪器计划的一部分，该项目支持明尼苏达大学（UMN）的新工具的获取 - 双城，用于对大气中有机化合物进行高度准确的测量。该仪器将在现场和实验室中使用。将收集数据的现场现场包括密歇根大学生物站的UMN高塔天文台和先知塔。从仪器中获得的新获取的数据将用于提高对土地大气系统中有机碳的生物地球化学的科学理解，重点是大气成分，土地 - 大气耦合的耦合，以及驱动空气污染和全球变化的过程。陆地大气碳交换和挥发性有机化合物（VOC）； （2）气相有机物的化学特性和老化； （3）有机气气溶胶相互作用； （4）土壤中有机碳生物地球化学。该乐器还将支持明尼苏达大学的土地和大气科学（LAAS）计划的研究生和本科生的教育。
