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.

该项目将在大型影响区域和全球环境（Mirage/Milagro）项目期间提供基于地面的气溶胶和痕量气体的测量。这些乐器将部署在墨西哥城以北的地面超级场地。除其他各种共同的测量（包括对气溶胶有机成分的测量，挥发性有机化合物和有机硝酸盐的测量值），所得的数据和建模将提供非常详细的图像，可提供非常详细的浓度和浓度的浓度和变换，以使气体和微粒污染物在层次上的型号群体群体群体群体群体分析（COM ebormity spectry speptriped speptrive speptripers）。羟基自由基和过氧化物以及硫酸。颗粒 - 液体采样器（PILS）仪器将用于气溶胶的快速现场化学分析，其他仪器将测量气相氮氧化物。光化学框模型将用于合成这些数据。该项目将为佐治亚理工学院的几位研究生提供教育机会，还将与墨西哥科学家开发合作。
