A Lidar backscattering system has been operational since August, 2001, in São Paulo, Brazil, at the Center for Laser and Applications (IPEN/CNEN-SP) and collecting data for pollution monitoring and tropospheric studies as boundary layer evolution, aerosol optical properties and validation with other instruments. The system operates at 532 nm and has been upgraded to a Raman Lidar to extend the number of channel to at least two, namely: 355 nm and 387 nm. In our presentation we will hihlight the achievements and special data sets obtained with this system and debate about our future operational goals whithin the context of a Lidar network in Latin America.
