Monitoring of the troposphere by a backscatter lidar in buenos aires (34.6S / 58.5W): Overview of the multi year data set and implementation of new ir channels and depolarization capability

An elastic backscatter Lidar is in operation at Buenos Aires (34.6S, 58.5W) for more than 8 years now starting in August 1995. A large data set has been collected on atmospheric boundary layer (ABL), natural and anthropogenic aerosols, mid and high cirrus clouds. Different improvements have been mad...
