Data access information
  • Near-real-time Operational Geophysical Data Records (surface wind speed and waves, and a first estimates of Sea Surface Height Anomaly) are distributed within 3-5 hours from NOAA and EUMETSAT via GTS and EUMETCast, see https://navigator.eumetsat.int/search?query=jason
  • Off-line Interim Geophysical Data Record re-processed after CNES makes available the Precise Orbit Determination are distributed within 1-2 days, and statistically analysed Geophysical Data Records are distributed from archives within 2 months
