Since June 2005, the CEILAP Lidar Division has installed an atmospheric laboratory in the Patagonian city of Río Gallegos (51º 36’ S, 69º 19’ W), Argentina, for the measurements of stratospheric ozone, tropospheric and stratospheric aerosols and water vapour, with lidar remote sensing techniques. Other passive instruments to measure UV solar radiation are also installed in the same site (www.division.lidar.com.ar). In this paper we derive the stratospheric aerosol backscatter coefficient from the return signals of a DIAL (Differential Absorption Lidar) system for one case study between 11 and 35 km height, and then to analyze the variations that these aerosols produce in the stratospheric ozone profile.
