heal.abstract	A backscattering LIDAR system, the first of this kind in Brazil, has been set-up in a suburban area in the city of São Paulo (23°33' S, 46°44' W) to provide the vertical profile of the aerosol backscatter coefficient at 532 nm up to an altitude of 4-6 km above sea level (asl). The measurements have been carried out during the second half of the so-called Brazilian dry season, September and October 2001 and during the first half of the dry season in August and September 2002. The LIDAR data are presented and analysed in synergy with aerosol optical thickness (AOT) measurements in the visible region (532 nm) obtained by a CIMEL sun-tracking photometer (belonging to the AERONET network) for purposes of validation of the data. The LIDAR data were also used to retrieve the Planetary Boundary Layer (PBL) height, aerosol layering and the structure of the lower troposphere over the city of São Paulo, and allowed us to categorise the profiles according to three distinctive patterns followed by the meteorological conditions of each type of categorisation. Here we show these categorisations, how we defined them and their distribution over the period of measurements.	en
