10 Campaigns Participation to the Canadian ACE/EUREKA Arctic campaign 2012 (Feb-March) (with the help of Xiaoyi Zhao, U. of Toronto)  Ozone and NO 2 columns.  SAOZ and Canadian UV-Visible spectrometer comparisons.  Location: 80.80°N, 86.41°W Validation of SCIAMACHY/ENVISAT tropospheric NO 2 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 H 2 O measurements  Location : 44°N, 6°E  Number of days of measurements:25days

11 Scientific Activities 1.O 3 : version V2 finalised and published (Hendrick et 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.NO 2 : version V3 (under progress) - Spectral analysis settings as V2 version - Sunrise and sunset stratospheric AMF NORS WP4: NDACC UV-VIS WG recommendations for homogenisation

12 Scientific Activities O 3 loss evaluation in Arctic VPSC weighted by sunlit vortex and SAOZ Cumulated Ozone loss Interannual variability: Sensibility of O 3 loss to history of stratospheric temperature Record in 2011 (under progress for publication)

13 Scientific Activities Stratospheric total NO 2 columns changing from 2001-2007 Pastel et al., to be submitted in ACP Pastel et al., to be submitted in AMT Long term comparisons of SAOZ/NDACC UV-Vis spectrometer and satellites total ozone and NO 2 measurements at the southern tropics

14 Scientific Activities Tropospheric NO 2 columns Correction of the multiple scattering NO 2 tropospheric AMF Use of this method at Paris and OHP stations. Extension to La Réunion station under study
