Real-Time Size and Composition Aerosol Measurements on the NSF C-130 Aircraft and Integrated Data Analysis

该项目支持在2006年墨西哥大城市对区域和全球环境的影响（MIRAGE）运动和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大小分辨信息。对这些数据的分析将产生关于气溶胶的来源和成因及其在远距离传输过程中的变化的信息。将特别关注气溶胶的有机含量，通过结合几位研究人员进行空中测量、地面测量和包括盒模型和反轨迹分析在内的模型的数据。这些资料将解决有关气体/气溶胶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。

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.
