We consider the problem of reconstruc5ng the meso-­-scale features of the currents in the Eastern Levan5ne Mediterranean from combining in-­-situ and satellite al5metry data. Mathema5cally, this is an inverse problem where the objec5ve is to invert Lagrangian trajectories, which are posi5ons of driQers launched at sea, in order to improve the coarse Eulerian velocity, provided by the al5metry satellite measurements. We shall use a varia5onal assimila5on approach, whereby the Eulerian velocity

One important property of our approach is that it is model-­-free, hence inexpensive and can be easily cast into real-­-5me oceanic opera5onal products. Acknowledgement
