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.
