dc.description.abstractWe describe a comparison study of aerosol optical thickness (AOT) from numerical simulations using a regional atmospheric model with an elastic backscattering lidar operating at 532 nm and a sunphotometer belonging to the AERONET network at São Paulo (23º S 46º W) city, Brazil, a very populated urban area. The atmospheric model includes an aerosol emission, transport and deposition module coupled to a radiative transfer parameterization, which takes the interaction between aerosol particles and short and long wave radiation into account. A period of one week was taken as case study during the dry season (late August) when intense biomass burning activities occur in remote areas in South America, and meteorological conditions disfavor the pollution dispersion in the city of São Paulo. The situation showed points out how smoke from biomass burning in remote areas is transported to the Southeast part of Brazil and affects the optical atmospheric conditions in São Paulo. The numerical simulations are corroborated by in-situ measurements of Aerosol Optical Thickness.
