Processing Type

  • Near RealTime
    Produced from Near RealTime sensor data. Ancillary data for GHRSST like analysis SST, wind speed and sea ice are not waiting in progress.
  • Standard
    Produced from Standard sensor data. Ancillary data for GHRSST like analysis SST, wind speed and sea ice are waiting for 3 days from the observation date time.
