Abstract: This paper presents three aspects of air pollution in the city of Buenos Aires (Argentina). First, we describe the main features of air pollution climatology in the city: the characteristics of wind flow, atmospheric stability and mixing heights. Then, we present the results of the application of DAUMOD and ISCST3 atmospheric dispersion models to calculate spatial and temporal distributions of carbon monoxide and nitrogen oxides background concentrations. Finally, we present the main features of carbon monoxide concentrations observed in a narrow street canyon located downtown.

Keywords: air pollution climatology; air quality; atmospheric stability; Buenos Aires; Argentina; dispersion modelling; mixing height; urban air pollution; urban street canyon; wind flow; carbon monoxide; nitrogen oxide.
