'''Short description''':

The BLKSEA_MULTIYEAR_PHY_007_004 product provides ocean fields for the Black Sea basin starting from 01/01/1993. The hydrodynamic core is based on the NEMOv4.0 general circulation ocean model, implemented in the BS domain with horizontal resolution of 1/40º and 121 vertical levels. NEMO is forced by atmospheric fluxes computed from a bulk formulation applied to ECMWF ERA5 atmospheric fields at the resolution of 1/4º in space and 1-h in time. A heat flux correction through sea surface temperature (SST) relaxation is employed using the ESA-CCI SST-L4 product. This version has an open lateral boundary, a new model characteristic that allows a better inflow/outflow representation across the Bosphorus Strait. The model is online coupled to OceanVar assimilation scheme to assimilate sea level anomaly (SLA) along-track observations from Copernicus and available in situ vertical profiles of temperature and salinity from both SeaDataNet and Copernicus datasets. Upgrades on data assimilation include an improved background error covariance matrix and an observation-based mean dynamic topography for the SLA assimilation.
