             abstract = "This work describes the development of an urban vehicle emissions 
                         inventory for South America, based on the analysis and aggregation 
                         of available inventories for major cities, with emphasis on its 
                         application in regional atmospheric chemistry modeling. Due to the 
                         limited number of available local inventories, urban emissions 
                         were extrapolated based on the correlation between city vehicle 
                         density and mobile source emissions of carbon monoxide (CO) and 
                         nitrogen oxides (NOx). Emissions were geographically distributed 
                         using a methodology that delimits urban areas using high spatial 
                         resolution remote sensing products. This numerical algorithm 
                         enabled a more precise representation of urban centers. The 
                         derived regional inventory was evaluated by analyzing the 
                         performance of a chemical weather forecast model in relation to 
                         observations of CO, NOx and O3 in two different urban areas, 
                         S{\~a}o Paulo and Belo Horizonte. The gas mixing ratios simulated 
                         using the proposed regional inventory show good agreement with 
                         observations, consistently representing their hourly and daily 
                         variability. These results show that the integration of municipal 
                         inventories in a regional emissions map and their precise 
                         distribution in fine scale resolutions are important tools in 
                         regional atmospheric chemistry modeling.",
