TOPAZ
Towards an Operational Prediction system for
the North Atlantic European coastal Zones
Since Oct. 2004, the developments of the TOPAZ system are continued within the activites of the Mohn-Sverdrup Center / Nansen Center

2nd July 2007: TOPAZ is upgraded to its third version, with double horizontal resolution (11 to 16 km from the Arctic to the Equator) and assimilation of ice drift data from Ifremer. This upgraded system constitutes the Arctic system of the MERSEA v2 integrated system.
TOPAZ develops advanced data assimilation systems (The Ensemble Kalman filter) for a coupled primitive equation ocean circulation and marine ecosystem model for the North Atlantic and the Arctic Ocean with enhanced resolution in the coastal zones, assimilating satellite and in-situ data available for real time operational use.
The observations used are satellite observed Sea Level Anomaly (SLA), Sea Surface Temperature (SST), Sea-ice concentrations from AMSR-E, sea-ice drift products from CERSAT and Coriolis in-situ Temperature and Salinity profiles.
The major outcomes in terms of products are short term forecasts issued weekly, open for public access and end users.
