CampaignsParticipation 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
Scientific Activities
1. O3: 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. NO2: version V3 (under progress)
- Spectral analysis settings as V2 version- Sunrise and sunset stratospheric AMF
NORS WP4: NDACC UV-VIS WG recommendations for homogenisation
Scientific ActivitiesO3 loss evaluation in Arctic
VPSC weighted by sunlit vortex and SAOZ Cumulated Ozone loss
Interannual variability: Sensibility of O3 loss to history of stratospheric temperature Record in 2011
(under progress for publication)
Scientific Activities
Stratospheric total NO2 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 NO2 measurements at the southern tropics
Scientific ActivitiesTropospheric NO2 columns
Correction of the multiple scattering
NO2 tropospheric AMF
• Use of this method at Paris and OHP stations.• Extension to La Réunion station under study
