Title: French contribution to ozone research and monitoring


1
French contribution to ozone research and
monitoring
S. Godin-Beekmann Service dAéronomie IPSL,
CNRS, Paris, France
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

NDACC measurements at Alpine station
Haute-Provence 44N, 6E
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)
Also Spectral UV radiometer in Villeneuve dAsq
(50N, 3E), Bordeaux Dobson spectrometer moved
to Lannemezan (43N, 0.1E)

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

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
