'''Short description :'''

This CMEMS Baltic Sea Biogeochemical Reanalysis product provides a biogeochemical 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) coupled with the biogeochemical model SCOBI (Swedish Coastal and Ocean Biogeochemical model) together with a LSEIK data assimilation scheme. All variables are available as daily means as well as monthly means, and include nitrate, phosphate, ammonium, dissolved oxygen and chlorophyll-a. The observation types used in the data assimilation are nitrate, phosphate, ammonium, and dissolved oxygen. 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.
