AB: The Aerodyne Research, Inc. (ARI) mobile laboratory was deployed in the Mexico City Metropolitan Area (MCMA) for the full month of March 2006 to support the MCMA-2006/MAX-Mex/MILAGRO research project activities, in collaboration with other MCMA-2006 research groups (see information on MCMA-2006/MILAGRO posted at http:www.mce2.org). The ratios of various volatile organic compounds (VOCs) to combustion tracer species such as CO and CO₂ are compared at one of the supersites (T0) and Pico de Tres Padres. T0 (located at the Mexican Petroleum Institute, IMP) is heavily influenced by various emission sources in the local area, predominantly roadway traffic. Pico de Tres Padres is an isolated, privately owned mountain located within the Mexico City Metropolitan Area (MCMA). It rises 1000 m above the MCMA basin floor and is located about halfway between T0 and T1. The airmasses analyzed at Pico de Tres Padres seem to be mixed urban emissions absent of high frequency spikes of CO, NO or CO₂. Relationships between VOCs, and combustion tracers will be used to gain a crude understanding of the initial photochemical processing of the urban emissions. How the initial photochemical processing of Mexico City's air may relate to secondary aerosol production is also explored.
