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.

该项目将对2003年MCMA（墨西哥城大都会地区）和即将举行的2006年广告系列的数据进行详细分析。 2003年的数据收集得到了能源部（DOE）和NSF的支持，该项目部分基于该项目的2006年基于地面的测量值将得到DOE的支持。 MCMA -2006将成为Milagro（墨西哥城倡议 - 地方和全球研究观察结果）的一部分。要分析的数据集包括表征细原发颗粒的发射通量，高度时间分辨的环境细颗粒（主要和次要）化学组成，尺寸分布和质量负荷；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。该分析将提供有关主要机动车辆精细颗粒排放和环境次级细颗粒的大气光化学产生的作用和相对重要性的详细信息。测量值以及城市规模和区域模型将解决运输，混合，化学和损耗过程对有机气溶胶浓度和性能进化的影响的问题。该项目将有助于培训许多学生，并促进美国和墨西哥研究机构之间的合作。
