Interpretation of validation results
Forecast only
The forecast is the deterministic part of the ARC-MFC PHY_ICE (neXtSIM) simulation, which starts one day before the bulletin date. There is one 10 day forecast for each bulletin date. The ARC-MFC PHY_ICE best estimate is not considered in the present monitoring configuration.
Uncertainties in the products
Instrument observations are never perfect representations of the true state. The observational product for sea ice type is derived from an adavanced, complex algorithm. Thus, it is likely that the observational uncertainty is significant. A more detailed presentation of the error sources are provided in this presentation, which was given at the general assembly of the European Geophysical Union in 2017.
