A version of the MOBILE6 motor vehicle emission factor model has been developed for use in Mexico. MOBILE6-Mexico incorporated Mexico-specific data into the MOBILE6 emission factor model previously developed by the U.S. Environmental Protection Agency. Experience gained during the previous development of Mexico-specific versions of the MOBILE4 and MOBILE5 models proved valuable in the development of the MOBILE6 model. Emission factors estimated by MOBILE6 were used to develop municipality-level motor vehicle emission estimates for the Mexico National Emissions Inventory (NEI) project. Draft results for the six northern Mexican states of Baja California, Sonora, Chihuahua, Coahuila, Nuevo León, and Tamaulipas were completed in July 2003 (these results are presented in a companion presentation by Fields).
This presentation will focus on the overall development process of the MOBILE6-Mexico model. The process will be presented in a step-by-step fashion, showing how parts of the U.S. model were adapted to the Mexican context. A detailed discussion of the Mexico-specific data used to develop the model will be provided. Differences between the new model and the previously developed MOBILE5-Mexico will be discussed, as well as areas of potential future improvement.
