Ocean Surface Topography Products from Jason-2 and Jason-3

The interagency Jason-2 and Jason-3 missions are joint efforts by four organizations to measure sea surface height by using a radar altimeter mounted on the low-earth orbiting satellites called Jason-2 and Jason-3. The four mission participants are:

  • National Oceanic and Atmospheric Administration (NOAA)
  • National Aeronautics and Space Administration (NASA)
  • France's Centre National d'Etudes Spatiales (CNES)
  • European Meteorological Satellite Organisation (EUMETSAT)

This satellite altimetry missions provide sea surface heights for determining ocean circulation, climate change and sea-level rise. The Jason-2 and Jason-3 satellites are the follow-on to the research satellites TOPEX/Poseidon and Jason-1 and are instrumental in meeting NOAA's operational need for sea surface height measurements necessary for ocean modeling, forecasting El Niño / La Niña events, and hurricane intensity prediction.
