OCEAN MODEL DIAGNOSTICS

Comparison of different ocean models, covering the arctic area. Including analyses, forecasts and observations.

Info about the models:

TOPAZ	MyOcean ARCMFC. The operational TOPAZ4 Arctic Ocean system uses the HYCOM model at 12 km resolution and a 100-member EnKF assimilation scheme. It is run daily to provide 10 days of forecast (one single member) of the 3D physical ocean, including sea ice; data assimilation is performed weekly to provide 7 days of analysis (ensemble average). More info here.
ROMS A20	ROMS model running at met.no, covering the Arctic and North Atlantic area, at 20 km resolution. Delivering daily 8-days forecasts. More info here.
ROMS N4	ROMS model running at met.no, covering the North Atlantic area, at 4 km resolution. Delivering daily 8-days forecasts. More info here.
ROMS NK800	ROMS model running at met.no, covering the Norwegian coastal area, at 800m resolution. Delivering daily 8-days forecasts. More info here.
FOAM	Global model system running at NCOF, using NEMO model at 1/4 degree resolution. More info here.
GLOBAL	MyOcean GLOMFC. The Mercator Ocean Global Ocean 1/12 and 1/4 and Atlantic Ocean 1/12 degree forecasting system uses the NEMO (Nucleus for European Models of the Ocean) modeling system, coupled to the thermodynamic-dynamic sea ice model LIM2 (Louvain sea Ice Model 2). More info about NEMO here.
OSISAF icec observations	Daily sea ice concentration analysis provided by the EUMETSAT OSISAF project.
OSTIA sst observations	The Operational Sea Surface Temperature and Sea Ice Analysis (OSTIA) system is run by the UK Met Office and produces a high resolution (1/20deg. - approx. 5km) daily analysis of the current sea surface temperature (SST) for the global ocean. OSTIA uses satellite data provided by the GHRSST project together with in-situ observations, to determine the sea surface temperature. More info here.
metno sst observations	MyOcean OSISST-TAC. Daily Arctic SST analysis performed by met.no. More info here.

The output from the different models is not directly comparable, as the definition of SSH may not be the same in all models.
