The results of an emission inventory of CO and NOx for the Buenos Aires Metropolitan Area (BAMA) are presented. The inventory includes area source emissions: residential, commercial, small industries, road traffic and aircrafts landing/take-off at both the domestic and the international airports. The inventory has a spatial resolution of 1 x 1 km. The emission factors used are based on measurements of in-service emissions in Buenos Aires and on the recommended by US. Environmental Protection Agency and the European Enviroment Agency. These factors were applied to fuel consumption, gas supply data and vehicle kilometres travelled within each grid square. Data on traffic flow and bus service frequencies were also available. We obtained spatial and time dependent area source emission distributions in the BAMA. Annually, 99.4% of CO and 80.6% of NOx area source emissions within the BAMA can be allocated to road transportations.
