MyOcean Arctic MFC: V0 Validation of sea surface temperature
Validation based on data from drifting buoys
Validation of the MyOcean Arctic MFC results for sea surface temperature is performed using data from drifting buoys, which are compiled by the MyOcean SST TAC. New sets of buoy data are available weekly. The buoy data are available with a temporal resolution of 3 hours. These data are converted to daily mean values to conform with the TOPAZ model results. Note that the analysis is not restricted to night-time data.
Buoy data are available from IFREMER-Coriolis who operates the MyOcean SST TAC.

Validation based on data from satellites
Validation of the MyOcean Arctic MFC results for sea surface temperature is performed using AATSR data from satellites.
Description will be added later
This validation is currently under implementation and testing - for demonstration only

Regions
The ocean circulation model used in myOcean's Arctic MFC covers the Arctic Ocean, the North Atlantic Ocean and adjacent ocean regions. The northern part is depicted in the figure below. Validation of sea surface temperature from model results is performed for three domains:
- an extended domain indicated by the blue, green and red regions in the figure
- the Nordic Seas, shown as the green region
- the Barents Sea, depicted in red
TOPAZ
The model results are produced with the TOPAZ ocean data assimilation model system. Presently, TOPAZ is run weekly with data assimillation one week prior to the bulletin date, followed by a one-week 100 member ensemble simulation ending on the bulletin date, and finally a 10 day deterministic forecast. TOPAZ was developed and is maintained by the Nansen Center.
For the validation of sea surface temperature, model results for ocean temperature at the 5 meter level are used.
TOPAZ results are available as aggregated, best estimates, and as a list of Bulletin dates with separate forecasts.
