This project will provide detailed analysis of data from the MCMA (Mexico City Metropolitan Area) 2003 and upcoming 2006 campaigns. The data collection in 2003 was supported by the Department of Energy (DOE) and NSF, and the 2006 ground-based measurements, on which this project is partly based, will be supported by the DOE. MCMA-2006 will be part of the MILAGRO (Mexico City Initiative - Local and Global Research Observations) integrated field program. The dataset to be analyzed includes the characterization of emission fluxes of fine primary particles, highly time-resolved ambient fine particles (primary and secondary) chemical composition, size distributions, and mass loadings; and extensive real-time measurements of secondary aerosol precursor gas emission sources and ambient concentrations. This analysis will provide detailed information on the roles and relative importance of primary motor vehicle fine particle emissions and atmospheric photochemical production of ambient secondary fine particles. Measurements as well as urban-scale and regional models will address the question of the influence of transport, mixing, chemistry, and loss processes on the evolution of organic aerosol concentrations and properties. This project will contribute to the training of a number of students, and foster collaborations between U.S. and Mexican research institutions.

该项目将详细分析2003年墨西哥城都会区(MCMA)和即将到来的2006年宣传活动的数据。2003年的数据收集工作得到了能源部和国家科学基金会的支持，2006年的地面测量是该项目的部分基础，能源部将为其提供支持。MCMA-2006将是米拉格罗(墨西哥城倡议--地方和全球研究观察)综合实地方案的一部分。要分析的数据集包括描述细一次颗粒物、高度时间分辨的环境细颗粒物(一次和二次)化学成分、粒度分布和质量负荷的排放通量；以及对二次气溶胶前体气体排放源和环境浓度的广泛实时测量。这一分析将提供关于一次机动车细颗粒物排放和环境二次细颗粒物的大气光化学产生的作用和相对重要性的详细信息。测量以及城市尺度和区域模式将解决运输、混合、化学和损失过程对有机气溶胶浓度和性质演变的影响问题。该项目将有助于培训一批学生，并促进美国和墨西哥研究机构之间的合作。
