An ultra-high resolution circulation model (0.125 nautical mile grid) of the Southeastern Baltic Sea is compiled from the General Estuarine Transport Model (GETM) in order to simulate the mesoscale eddy field in the area. The model results are compared with optical and infrared satellite imagery available for the period of May-August 2015. Mesoscale eddies detected in the satellite images are reasonably well identified in the simulated patterns of the sea surface temperature, currents, and floating Lagrangian particles.
