1 WMO/UNEP 7th ORM, Geneva 18-21 May 2008 1 French contribution to ozone research and monitoring S. Godin-Beekmann Service dAéronomie – IPSL, CNRS, Paris, France

2 WMO/UNEP 7th ORM, Geneva 18-21 May 2008 2 Observational activities Long term ground-based measurements Contribution to NDACC : Alpine station, Antarctica (Dumont dUrville, Concordia), La Reunion Island (SH), SAOZ network (UV-Vis spectrometers) Balloon measurements Polar and tropical campaigns within EU projects (SCOUT-O3, AMMA) Aircraft measurements Regular O3 and CO measurements on board commercial aircrafts (MOZAIC programme) Satellite measurements

3 WMO/UNEP 7th ORM, Geneva 18-21 May 2008 3 NDACC measurements at Alpine station Ozone Dobson (1983), ozone sondes (1984) Lidars (strato O3 – 1985; tropo 1991), SAOZ UV-Vis spectrometer (1992 - O3, NO2) Aerosol Lidar (1991), aeronet sun photometer (2004) Temperature Lidar (1979) Spectral UV spectrometer (moved from nearby Briançon) Haute-Provence 44°N, 6°E Also: Spectral UV radiometer in Villeneuve dAsq (50°N, 3°E), Bordeaux Dobson spectrometer moved to Lannemezan (43°N, 0.1°E)

4 WMO/UNEP 7th ORM, Geneva 18-21 May 2008 4 NDACC measurements in Antarctica Dumont dUrville Lidar (collaboration with Italy) Ozone (1991-1998; 2008) PSC (1989 – 1998; 2005 - present) Ozone sondes (since 1989) SAOZ UV-Visible spectrometer (1988) UV-B broadband Concordia (collaboration with Italy) New station since 2006 SAOZ UV-Vis spectrometer since 2007 Ozonesondes in 2007-2008 for IPY. Microwave radiometer for tropo H2O planned Dumont dUrville Concordia

5 WMO/UNEP 7th ORM, Geneva 18-21 May 2008 5 NDACC measurements in La Reunion Island Lidars Temperature, aerosol, tropo & strato ozone, aerosol Ozone sondes (SHADOZ) SAOZ: UV-Vis spectrometer New instruments: FTIR and MaxDOAS (IASB-BIRA) Microwave radiometer H2O New high altitude Maido station 2200 m – delivery end 2010

6 WMO/UNEP 7th ORM, Geneva 18-21 May 2008 6 SAOZ network observations and passive ozone tracer from a CTM Chemical ozone loss estimation in the Arctic UV/Visible spectrometers : 15 stations globally distributed

7 WMO/UNEP 7th ORM, Geneva 18-21 May 2008 7 Satellite Satellite instruments & retrieval algorithm In collaboration with other EU institutions ODIN SMR (2001): microwave radiometer O3, ClO, N2O, H2O GOMOS - ENVISAT (2002) solar spectrum, stellar occultation O3, NO2, NO3, OClO, temperature, water vapour IASI – METOP (2006) infrared spectrometer Nadir total ozone, o3 partial columns, CO, CH4, H2O, clouds Satellite products validation GOME, ENVISAT (GOMOS, SCIAMACHY, MIPAS), Aura, (MLS, HIRDLS) Long term ENVISAT validation activities (EQUAL, TASTE) Trend validation (multiple satellite missions) ozone recovery, temperature trends, intercalibration
