Black Sea Physical Analysis and Forecast (Copernicus Marine Service BLK-PHY, EAS6 system)

The Copernicus Marine Black Sea Physics Analysis and Forecast product is based on the NEMO v4.2.1 ocean circulation model, online coupled with WaveWatch III v6.0.7. It uses a variational data assimilation scheme called OceanVar, able to assimilate temperature and salinity vertical profiles, satellite SLA along track data and satellite SST data from Copernicus Marine associated TACs. The model has a 1/40˚ regular horizontal grid resolution and 121 unevenly spaced vertical levels. The model implements open boundary conditions at the Marmara Sea box for the optimal interface with the Mediterranean Sea by using high resolution model solutions provided by the Unstructured Turkish Strait System (U-TSS) model. Results from the U-TSS model for the Marmara Sea are interpolated onto a 1/160° regular horizontal grid and provided as additional datasets within the Black Sea product.
