This project is designed to conduct a comprehensive set of measurements of the optical and physical properties of aerosol particles using an instrument suite operated 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). The instrument suite includes Condensation Nuclei Counters (CNCs), a Tandem Volatility Differential Mobility Analyzer (DMA), Optical Particle Counters (OPCs), aerodynamic particle sizing, a three-wavelength nephelometer, a three-wavelength particle soot absorption photometer (PSAP), and a Fast Mobility Particle Sizer (FMPS). This combined instrumentation suite will allow measurements of ambient in-situ aerosol size-distributions, microphysical and optical properties, and physio-chemical characteristics. The results will be used to improve the understanding of changes in the mixing state of aerosols and their physical, chemical and optical properties over the urban-to-regional-to-global transition, and to verify and refine the interpretation of model and satellite products. One post-doctoral student and one graduate student will receive support under the auspices of this project. Both will be involved in the field campaigns and in subsequent data analysis. Final data will be made available to the community via data archives and websites.

该项目的目的是在2006年墨西哥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，使用NSF C-130飞机上运行的仪器套件，对气溶胶颗粒的光学和物理特性进行一套全面的测量。该仪器套件包括冷凝核计数器（cnc），串联挥发性差分迁移率分析仪（DMA），光学粒子计数器（OPCs），空气动力学颗粒大小，三波长浊度计，三波长颗粒烟灰吸收光度计（PSAP）和快速迁移率粒度仪（FMPS）。该组合仪器套件将允许测量环境原位气溶胶尺寸分布、微物理和光学特性以及物理化学特性。这些结果将用于提高对城市-区域-全球过渡期间气溶胶混合状态及其物理、化学和光学性质变化的理解，并验证和改进模式和卫星产品的解释。资助博士后1名，研究生1名。两者都将参与实地活动和随后的数据分析。最终数据将通过数据档案和网站提供给公众。
