This project will provide ground-based measurements of aerosols and trace gases during the Megacity Impacts on Regional and Global Environments (MIRAGE/MILAGRO) project. The instruments will be deployed at the ground-based super site north of Mexico City. Along with various other collocated measurements (including NSF-supported measurements of aerosol organic composition, volatile organic compounds, and organic nitrates), the data obtained and modeling performed will provide a very detailed picture of the concentrations and transformations of gaseous and particulate pollutants in the outflow region of a Megacity.A Chemical Ionization Mass Spectrometer (CIMS) will be deployed to measure hydroxyl radical and peroxides, as well as sulfuric acid. A Particle-Into-Liquid Sampler (PILS) instrument will be used for rapid in-situ chemical analysis of aerosols, and additional instruments will measure gas-phase nitrogen oxides. Photochemical box models will be applied to synthesize these data.This project will provide educational opportunities for several graduate students at the Georgia Institute of Technology, and will also develop collaborations with Mexican scientists.

该项目将在“超大城市对区域和全球环境的影响”（MIRAGE/MILAGRO）项目期间提供气溶胶和微量气体的地面测量。这些仪器将被部署在墨西哥城北部的地面超级站点。随着各种其他的同步测量（包括美国国家科学基金会支持的气溶胶有机成分，挥发性有机化合物和有机硝酸盐的测量），获得的数据和执行的建模将提供一个非常详细的图像，气体和颗粒污染物的浓度和转化在一个特大城市的流出区。化学电离质谱仪（CIMS）将用于测量羟基自由基和过氧化物以及硫酸。粒子进液采样器（PILS）将用于气溶胶的快速原位化学分析，另外的仪器将测量气相氮氧化物。将应用光化学盒模型对这些数据进行综合。该项目将为佐治亚理工学院的几名研究生提供教育机会，并将与墨西哥科学家开展合作。
