The impact of assimilating along-track sea level anomaly (SLA) data into a regional Hybrid Coordinate Ocean Model (HYCOM) is investigated with regard to the simulation of mesoscale eddy characteristics in the Agulhas System. Eddy characteristics from an assimilated (Assim) and an unassimilated (Free) simulation experiment in HYCOM are compared with each other, using satellite altimetry derived eddy characteristics as a basis to evaluate accuracy. Overall, Assim yields improvements over Free in eddy density distribution and dynamics. South of Madagascar, the number of eddies simulated by both HYCOM experiments is too low, although Assim offers some improvements in this regard.
