Application of Back-Trajectory Techniques to the Characterization of the Regional Transport of Pollutants to Buenos Aires, Argentina
Backward trajectories from Buenos Aires, Argentina, were used in an exploratory study to characterize the airflow and the relationship with synoptic patterns and to contribute to the identification of air pollution source regions. Buenos Aires is the most populated city of the country. Air pollution climatology studies have shown that there is an important frequency of reduced ventilation conditions, especially during the cold season (Ulke, 2000). Case studies have demonstrated the transport of biomass burning products from Brazil during the tropical dry season toward the region (Longo et al, 1999).
