Abstract

A lidar system has been operational at Sao Paulo, Brazil (23° S, 46° W) since 2001 and colocated is a sunphotometer belonging to AERONET . During this last years aerosol properties has been extracted from both systems and seasonal trends have been observed specially when long range transport takes place bringing plumes with biomass burning aerosol which can distinctively be extracted from a heavy loaded atmosphere as São Paulo. These events trigger poor air quality conditions which can be easily correlated. The parameters for studying these patterns are Aerosol Optical Depth, Angström Exponent and Lidar Ratio. We show here some case studies belonging to years 2003, 2004 and 2005.
