Resumen:
Results obtained in the study of relationships between the dispersion mechanisms in southeastern South America and particle pollution in Buenos Aires are presented. The research aims to increase the knowledge on features and behavior of aerosols in the atmosphere of Buenos Aires city and to discriminate the local and remote contributions.Numerical modeling tools are applied combined with the study of meteorological conditions and the analysis of the aerosol properties. Aerosols in Buenos Aires are due to local urban and industrial sources and those related with distant sources such as biomass burning, resuspended dust from arid regions, marine aerosols, aerobiological material and volcanic eruptions. Aerosol properties obtained with remote sensing techniques or from in-situ surface sampling are analyzed. Features and variability of the aerosol properties in Buenos Aires clearly show the influence of regional flow patterns and atmospheric dispersion conditions.
