Now a day we have strong evidence that human activities link to industrialized process have perturbed the natural balance of atmosphere composition. This fact has produced global scale issues like ozone depletion around the globe. The stronger manifestation of this phenomenon is the Antarctic ozone depletion today well known as ozone hole. Subpolar regions as the Patagonia, Argentina, in the southern part of South America are affected by this phenomenon, covered sometimes by air masses with less ozone than normal with the corresponding UV enhancements at ground surface. Motivated by these atmospheric events, Argentine, Japanese and French researchers cooperated to carry out field campaigns with the objective to monitor atmospheric species and parameters at southern part of Argentina. Since June 2005, the CEILAP Lidar Division, with the financial support of JICA (Japan International Cooperation Agency) and the collaboration with IPSL, France, has installed an atmospheric laboratory in the Patagonian city of Río Gallegos (51º 36’ S, 69º 19’ W) for the measurements of stratospheric ozone, aerosols and water vapour with lidar remote sensing techniques. During 2005-2006 springs, the SOLAR Campaign was carried out, giving the opportunity to measure the evolution of stratospheric ozone profiles and the influence of polar vortex overpass over southern part of Argentina. In this paper we present same results of lidar ozone measurements made during this field campaign, the first one carry out in Argentina using lidar technologies.
