  1. Río Gallegos Site,Argentina Collaboration between CEILAP, LATMOS-IPSL and JICA New NDACC station in SH hemisphere Centro de Investigaciones en Láseres y Aplicaciones (LASER RESEARCH CENTER AND APPLICATIONS ) (CITEFA-CONICET) Buenos Aires - Argentina

  2. Río Gallegos Site (CEILAP-RG) Province of Santa Cruz, Argentine Patagonia. Lat: 51º 36’ S, Lon: 69º 19’ W. Military Air Force Base, Río Gallegos - Fuerza Aérea Argentina (FFAA)

  3. Little History of RG Site Events DIAL Ozone Instrument Ready to measure Admission of DIAL Ozone Inst. To NDACC Network Start with UVO3Patagonia Project Transportation Of Instrument to Rio Gallegos Site First Ozone Sonde Campaign in Río Gallegos Events SOLAR Campaign Mar 2010 2004 Jun 2005 Aug 2005-Dec 2006 Sep 2007 Dec 2008 Time

  4. Intercomparison Campaign Río Gallegos 2010 Argentina – Chile collaboration 3 sondes launched in Río Gallegos site, collocated with DIAL during first week of March

  5. Time Evolution of Total Ozone in Río Gallegos (2009) Study case 1 (October 3 and 4) Prolonged O3 Reduction Extreme Event (November 2009)

  6. OMI/AURA Study Case 1 of Ozone Hole overpass in RG Site during 2009 Oct 2 2009 Oct 4 2009 Oct 6 2009

  7. New Capability of Temperature Lidar Profile in RG SiteComparison Lidar with HIRDLS/AURA-NASA ΔS < 500 Km ΔT ± 12 Hs Temperature Profiles With Correction by Aerosols using Lidar Rayleigh Mean ± 1σ dev HIRDLS Temperature Profiles Without Correction by Aerosols using Lidar Rayleigh 1 Km Resolution HIRDLS N = 94 Measurements Error bars are plus and minus 1σ dev

  8. UVI & partial ozone loss column changes ► Regions R1 & R6, the most affected by vortex occurrences & polar ozone loss Maximum UV increase are observed in region R1 due to low cloud clover conditions If changes in cloud clover, R6 is the most sensitive region ► ► October (no cloud discrimination) Regions of potential UV enhancements linked to vortex occurrences in a cloudiness diminution scenario Vortex occurrences TOC changes October (quasi-clear sky) Vortex occurrences TOC changes UVI changes [40°S-60°S] latitude band

  9. spring 2002 Evolution of chemical ozone loss over Antarctica since 1980 Increased variability since 2000 1st major warming observed over Antarctica: split of the polar vortex and the ozone hole Polar region: Antarctica 2006 2004 2002

  10. Perspectives • Monitoring of atmospheric composition at Rio Gallegos (ozone, aerosol, UV, temperature) • Very few measurement stations in the SH for long term trend studies and cross-validation of satellite time series • Network for the Detection of Atmospheric Composition Changes (NDACC) southern mid-latitudes stations: Lauder (NZ) and Rio Gallegos (Argentina) • More instruments are being implemented (microwave radiometer, U. Nagoya) • Study of the recovery of the Antarctic ozone hole in relation with climate change
