Resumen:
The Atmospheric Observatory of Austral Patagonia (OAPA) is a remote sensing site located near the Río Gallegos city in South Patagonia (51º 55’S, 69º 14’W), in subpolar region affected by the polar vortex. It a convenient monitoring site of the atmosphere in the southern hemisphere especially for ozone studies. This site is operative a differential absorption lidar instrument (DIAL) for the measurement of ozone vertical distribution. This instrument is part of Network Data for Atmospheric Composition Change (NDACC). The altitude range of the ozone measurement is 14-45 km, which provides the opportunity to monitor the perturbations due to the passage of stratospheric polar air over Río Gallegos. Since 2005, systematic stratospheric ozone profile measurement has been carried on in this experimental site. The position of station with respect to the polar vortex was made through the use of equivalent latitude maps. We identified three mayor perturbation of ozone hole over the stratospheric ozone profile in Río Gallegos: approximation of polar vortex during late winter, overpass of ozone hole in middle spring and dilution process during late spring. All these three process change the shape stratospheric ozone profile and produce variation in the total ozone column over the OAPA. These perturbations in the middle atmosphere induce change in solar UV radiation at ground surface of great importance for life. In this article we review the main conclusion regarding the observation of stratospheric ozone profiles measurements OAPA for the period 2005-2011.
