Baltic Sea Physics Reanalysis

'''Short description:''' This CMEMS Baltic Sea Physical Reanalysis product provides a physical reanalysis for the whole Baltic Sea area, inclusive the Transition Area to the North Sea, from January 1993 and up to minus 1-1.5 year compared to real time. The product is produced by using the ice-ocean model NEMO-Nordic (based on NEMO-3.6, Nucleus for European Modelling of the Ocean) together with a LSEIK data assimilation scheme. The surface variables are available every hour and include sea surface height, ice concentration and total ice thickness. The other variables, available as daily and monthly means, are salinity, temperature, horizontal current components, mixed layer depth, bottom salinity and bottom temperature. The observation types used in the data assimilation are sea surface temperature and profiles of salinity and temperature. The reanalysis has been produced using 72-hour cycling, which implies that every 72 hours, all available observations are assimilated into the model before a 72-hour forecast is made.
