             abstract = "This work describes the development of an urban vehicle emissions 
                         inventory for South America (SA), based on the analysis and 
                         aggregation of available inventories for major cities, with 
                         emphasis on its application in regional atmospheric chemistry 
                         modeling, for the study of chemical composition modification on SA 
                         and its impact on the regional climate change. This database 
                         integrates information from local inventories of vehicle emissions 
                         into existing global databases for the South American continent. 
                         Due to the limited number of available local inventories, urban 
                         emissions were extrapolated based on the correlation between city 
                         vehicle density and 2004 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, both important Brazilian 
                         metropolitan areas. 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. In addition, we are performing simulations for 
                         recent years in order to study the regional impact of the large 
                         urban areas in chemistry composition of South America.",
