AB:
MILAGRO (Megacity Initiative: Local and Global Research Observations) was a multi-agency field study that took
place in Mexico City during the month of March, 2006. One of the components is MCMA-2006, which focused on
the characterization of the emission of pollutants from the urban area, their transport and transformation. It is
intended to improve the understanding of atmospheric chemistry with a vast amount of observations and
incorporate into evaluation and design of air pollution related policies. The meteorological conditions were
categorized into 6 episodes; O3-North, O3-South, Cold Surge, South Venting, Convection South, and Convection
North. During an O3-South meteorological condition, previous study on the MCMA-2003 field campaign
suggested that the urban core region during ozone peak hours is VOC-limited. This presentation will examine
three major questions using O3-North meteorological condition as an initial case study for the MCMA-2006
campaign: 1) the reproduction of ozone precursors and ozone concentrations; 2) the sensitivity of ozone
production to the precursor emissions during the MCMA-2006 field campaign; and 3) the comparison to the
MCMA-2003 field campaign. Concentrations of air pollutants will be simulated using the Comprehensive Air
Quality Model, with extensions (CAMx v4.40).
