About SWOT mission

SWOT’s advanced imagery allows to measure the height of water on over 90% of Earth’s surface, providing a high-resolution survey of our planet’s water for the first time. The SWOT’s Ka-band Radar Interferometer instrument KaRIn collects 2D measurements of surface ocean topography at spatial scales on the order of 15-150 km over a swath about 50 km wide on either side of the satellite, in addition to traditional along-track measurements carried out by a nadir-looking (Poseidon-3C) altimeter.
SWOT is a joint mission between NASA and CNES, with contributions from the Canadian Space Agency (CSA) and United Kingdom Space Agency (UKSA). For further information on the SWOT mission objectives and ongoing activities, you can visit the AVISO+ website.

SWOT applications

  • High resolution global ocean altimetry
  • Coastal currents and processes
  • Oceanic mesoscale and sub-mesoscale processes
  • Ocean Bathymetry

SWOT data usage

SWOT data products are made freely available by the SWOT project and the national programs that contribute to it. SWOT product quality is not final and will be affected by some evolutions as the SWOT project team makes progress on science data processing algorithms and instrument calibrations.

Users are advised of the following upcoming changes in the datasets:


    July 2023:
  • The production and distribution of GDR (O/I) products will be temporarily suspended from July 11, 2023 to allow the platform to be transferred to scientific orbit. Users will be informed when service resumes.
  • Ground instrument corrections will be updated when production resumes after the orbit change (MLE3 and MLE4 retrackers).
  • The orbit status flag will be improved when production resumes after the orbit change.

    • September 2023:
  • Production and release of O/I(GDR) products have resumed in nominal conditions.
  • Distribution of the OGDR science data products resumes from September 7, 2023 and onwards.
  • Distribution of the IGDR science data products starts from July 21, 2023 and onwards.
