Satellite Data and Services Center CERSAT


The CERSAT (Centre d’Exploitation et de  Recherche SATellitaire) centre is dedicated to the provision to the scientific user community of advanced satellite datasets with a focus on air-sea interface and the combination of multiple sensors. It is based in Brest, managed by Ifremer and operated jointly though two supporting departments : IRSI for production and dissemination, and the LOPS (Laboratoire d’Oceanographie Physique et Spatiale) for the development and validation of the scientific datasets.

The delivered datasets come from processing chains developed and operated internally or through associated entities, such as Météo-France/CMS, and multi-partner projects funded by organizations such as ESA, Eumetsat, CNES, CMEMS, etc.... They range from data delivered in near real time to long and homogeneous time series of essential climate variables.

Physical Oceanography

  • Sea surface temperature
  • Sea surface salinity
  • Ocean currents
  • Waves (SWH and directional spectra)
  • Ocean Winds
  • Sea ice drift and sea ice types
  • Icebergs
  • Turbulent fluxes
  • Ocean color

Access to data through the ODATIS catalog

CERSAT Data and Services Centre provides data products using and combining observations from several passive and active satellite missions:

  • CFOSAT (wind and waves), through IWWOC project
  • SMOS (salinity and soil moisture), through CATDS project
  • IR and MW radiometers (sea surface temperature): Metop-A, Metop-B, MSG,…
  • Altimeters (ocean wave, icebergs) : ERS-1, ERS-2, Topex-Poseidon, GFO, Envisat, Jason-1, Jason-2, Jason-3, CryoSat-2, Saral, Sentinel-3A, Sentinel-3B,...
  • Scatterometers (ocean winds, sea ice) : ERS-1, ERS-2, NSCAT, QuikSCAT, SeaWinds, Metop-A, Metop-B, ScatSat, CFOSAT,…
  • Synthetic Aperture Radars (waves, wind) : ERS-1, ERS-2, Envisat, Sentinel-1A, Sentinel-1B,...
