In the framework of SAVER-Net project, the OZone profile aT Rio GallegOS (OZITOS+) campaign was held in the city of Rio Gallegos, Argentina (51.5 S; 69.1 W). This experiment was conducted on October 14-18, 2014 and its main goal was to compare the ozone and temperature profiles using three different measurement techniques such as Differential Absorption Lidar (DIAL), ozonesonde and Millimeter Wave Radiometer (MWR). Also other ground-based and satellite-based instruments were included in the experiment but in this work we only present preliminary results from ground-based instruments deployed in the site. The DIAL instrument is part of Network Data for Atmospheric Composition Change (NDACC) network, and the usual protocols of quality assurance imposed for the network involve regular validation/comparisons experiments. The lidar ozone profiles measured with the lidar are compared with ozone profiles obtained with independent techniques, usually with higher or same resolution as lidar. The experiment are made collocated spatial and temporally. For that reason the Chilean team joined to Japanese and Argentine team at Rio Gallegos to develop the experiment. On October 2014, the Rio Gallegos Observatory station was inside the polar vortex during first two weeks and after that polar vortex have moved far away from Rio Gallegos during the 3rd week of October, when the intercomparison campaign was held. In this paper we are present a preliminary results of the campaign, computing the ozone and temperature profiles from DIAL with ozonesondes and MWR.
