AB: Understanding the relation between ozone (O₃) and its precursors, nitrogen oxides (NO_x) and volatile organic compounds (VOCs), is a prerequisite for formulating an effective O₃ control strategy. In this study, a 3-D chemical transport model (CAMx) was used to investigate the characteristics of O₃ production and the response of O₃ production to changes in precursor emissions in the urban region of Mexico City Metropolitan Area (MCMA) under different meteorological conditions ("O₃ - South", "O₃ - North", and "Cold Surge"). Simulated concentrations of O₃, CO, NO_x and various speciated VOCs were compared with the measurements from MCMA-2003 Campaign. Uncertainties in the emission inventory were evaluated in the context of model-observation comparison. This study aims to present a comprehensive and coherent view of the O₃ production characteristics in the MCMA.
