IMPROVING THE ACCURACY OF THE BLACK SEA PHYSICS ANALYSIS AND FORECASTING SYSTEM IN THE FRAMEWORK OF COPERNICUS MARINE SERVICE

Abstract

This study will present the evolution of the Black Sea model physics in the framework of the Copernicus Marine Environment Monitoring Service, from EAS3 (current operational system) to EAS4 (operational from May 2021). EAS4 has been greatly improved thanks to new core model (based on NEMO v4.0), improved bathymetry and representation of rivers, revision of the spatial domain at higher resolution (2.5 km and 121 z-star-levels) to include the Marmara Sea box for the provision of the lateral open boundary conditions. For the optimal interface between Mediterranean and Black Sea though boundary conditions, a new high-resolution unstructured grid-based model has been developed for the Marmara Sea. Evolution in terms of modelling framework and prediction capacity will be detailed, describing the main results and skill score metrics.
