Expected applications are also Topex/Poseidon, Jason-1 and Jason-2's :

  • ocean study,
  • climate study, seasonal forecasting (including El Niño and such phenomena),
  • wind speed and wave height measurements, in real-time for weather forecast models, and over the long term (climatologies) for studies and model improvements,
  • better knowledge of the geoid, in combination with geodetic satellites (Grace, Goce),
  • Tide models improvements,
  • ...
