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

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
