Study of Some Aerosol Features in Buenos Aires

Abstract

We present the analysis of in-situ measurements obtained in an experimental campaign in Buenos Aires. Observations of total condensation nuclei (CN), black carbon (BC), polycyclic aro matic hydrocarbon concentration in particulate phase (PPAH), vertical profiles of aerosol light backscattering and meteorological parameters, were obtained at a coastal site during a one-year period. The study provides detailed and novel information about the contributions to the aerosol load in the at mosphere of Buenos Aires due to the co mbined act ion of a variety of sources and dispersion mechanisms. Furthermore, they provide a unique dataset to evaluate modeling tools.
