  6. Real time data ProvidingRT data at WMO Monthlynewsletter on state of the ozone layer N°1-2008 http://www.wmo.int/pages/prog/arep/gaw/ozone/index.html

  7. Data archived in NDACC data base Consolidated data (version V1: annual O3 and NO2 AMF) in NDACC-DHF Consolidated data (version V2:seasonal O3 AMF) in NDACC-DHF RT data (version V1) in SAOZ web page

  8. Data archived in NDACC data base (O3_N-O3_v2)/03_v2 Pi Kerstin Stebel Kertstin.Stebel@nilu.no Consolidated data (version V1: annual O3 and NO2 AMF) in NDACC-DHF Consolidated data (version V2:seasonal O3 AMF) in NDACC-DHF RT data (version V1) in SAOZ web page

  9. Fundings

  10. Campaigns • Participation to the Canadian ACE/EUREKA Arctic campaign 2012 (Feb-March) • (with the help of Xiaoyi Zhao, U. of Toronto) • Ozone and NO2 columns. • SAOZ and Canadian UV-Visible spectrometer comparisons. • Location: 80.80°N, 86.41°W • Validation of SCIAMACHY/ENVISAT tropospheric NO2 in Paris (starting Dec. 2004) • SAOZ instrument on the roof of University UPMC in the city of Paris, France. • Location: 48.84°N, 2.34°E • Number of days of measurements: 361 • DEMEVAP campaign in OHP (Dec. 2011) • Tropospheric H2O measurements • Location : 44°N , 6°E • Number of days of measurements:25days

  11. Scientific Activities NORS WP4: NDACC UV-VIS WG recommendations for homogenisation • 1. O3: version V2 finalised and published (Hendricket al., ACP, 2011) • - Spectral analysis settings (impact <1%) • - Air Mass Factor (significant impact, specially polar regions) • Test by comparison between 8 SAOZ stations / 20 years distributed in latitude and all available nadir viewing satellites • Important to correct in the future, satellite (and Dobson /Brewer) total ozone retrievals for T and SZA dependences • 2. NO2: version V3 (under progress) • - Spectral analysis settings as V2 version • - Sunrise and sunset stratospheric AMF

  12. Scientific Activities O3 loss evaluation in Arctic VPSC weighted by sunlit vortex and SAOZ Cumulated Ozone loss Interannualvariability: Sensibility of O3 loss to history of stratospheric temperature Record in 2011 (under progress for publication)

  13. Scientific Activities Long term comparisons of SAOZ/NDACC UV-Vis spectrometer and satellites total ozone and NO2 measurements at the southern tropics • Pastel et al., to be submitted in AMT Stratospheric total NO2 columns changing from 2001-2007 • Pastel et al., to be submitted in ACP

  14. Scientific Activities Tropospheric NO2 columns Correction of the multiple scattering NO2tropospheric AMF • Use of thismethodat Paris and OHP stations. • Extension to La Réunion station understudy
