This project involves making measurements of non-methane hydrocarbon, carbon monoxide and NOy fluxes in the center of Mexico City during the Megacity Impacts on Regional and Global Environments (MIRAGE), the Mexico City Pollution Outflow Field Campaign. A range of flux measurement techniques will be employed to test the validity of the emissions inventory for volatile organic compounds in Mexico City. These techniques include the use of a Fast Olefin Sensor to measure olefin fluxes, a Proton Transfer Reaction Mass Spectrometer to measure fluxes of aromatics and selected oxygenated volatile organic compounds, and a novel disjunct eddy accumulation system to measure fluxes of other individual volatile organic compounds amenable to analysis with gas chromatography/flame ionization detection. Fluxes of carbon monoxide, carbon dioxide, and latent and sensible heat flux will also be included.Graduate and undergraduate students will receive training under the auspices of this project, exposing them to environmental issues associated with a megacity located in a developing country. Students will be involved in the field program and in analysis of the data from the field program. Results from the work will be used to illustrate megacity environmental impacts as part of undergraduate and graduate classes at Washington State University. The data base will become part of the Megacity Impacts on Regional and Global Environments data archive.

该项目涉及在墨西哥城污染外流实地活动“特大城市对区域和全球环境的影响”期间，对墨西哥城中心的非甲烷碳氢化合物、一氧化碳和NOy通量进行测量。将采用一系列通量测量技术来检验墨西哥城挥发性有机化合物排放清单的有效性。这些技术包括使用快速烯烃传感器来测量烯烃通量，质子转移反应质谱仪来测量芳烃和选定的氧化挥发性有机化合物的通量，以及一种新的分离涡流累积系统来测量其他个别挥发性有机化合物的通量，这些挥发性有机化合物适合于用气相色谱/火焰离子化检测进行分析。研究生和本科生将在该项目的赞助下接受培训，使他们了解与发展中国家特大城市有关的环境问题。学生将参与现场项目并分析现场项目的数据。这项工作的结果将作为华盛顿州立大学本科生和研究生课程的一部分，用于说明大城市的环境影响。该数据库将成为特大城市对区域和全球环境影响数据档案的一部分。
