This project supports the deployment of an aerosol mass spectrometer (AMS) with time-of-flight capability on the NSF C-130 aircraft during the 2006 Megacities Impacts on Regional and Global Environments (MIRAGE) Campaign to be conducted in Mexico City and the Intercontinental and Megacity Pollution Experiment (IMPEX). This project is being jointly supported by NSF and NASA.The AMS instrument will deliver size-resolved information on the chemical composition of aerosols. The analysis of these data will yield information on the sources and of the aerosols and their transformations as they undergo long-range transport. Special attention will be given to the organic content of the aerosols, by combining data by several investigators making airborne measurements, ground-based measurements, and models including box models and back-trajectory analysis.This information will address important questions about gas/aerosol evolution and properties and their climatic effects. The award will contribute to the education of a graduate student and a post-doctoral researcher.

该项目支持在墨西哥城进行的2006年大城市对区域和全球环境的影响(MIRAGE)活动以及洲际和大城市污染实验(IMPEX)期间，在NSF C-130飞机上部署具有飞行时间能力的气溶胶质谱仪(AMS)。该项目由美国国家科学基金会和美国国家航空航天局共同支持。AMS仪器将提供气溶胶化学成分的尺寸分辨信息。对这些数据的分析将提供有关气溶胶的来源和变化的信息，以及它们在进行长途运输时的变化情况。将结合进行空中测量、地面测量和包括箱式模型和反向轨迹分析在内的模型的几个调查人员的数据，对气溶胶的有机含量给予特别关注。这些信息将解决有关气体/气溶胶的演变和性质及其气候影响的重要问题。该奖项将用于培养一名研究生和一名博士后研究员。
