ESA 4DMED-Sea - Finite-size Lyapunov Exponents in the Mediterranean Sea derived from 4DVARNET20 geostrophic velocities (1/72°)

This product provides the Finite-size Lyapunov Exponents derived from surface geostrophic velocities result from the application of the 4DVARNET algorithm (Fablet et al., 2021; resolution of the dynamical model used for the learning/training (eNATL60-BLB02) downgraded to 1/20°) to altimetry L3-data (https://doi.org/10.5281/zenodo.10912777) at a resolution of 1/72° over the Mediterranean Sea and for the period from April 2016 to July 2022. 

Algorithm used to compute Finite-Size Lyapunov Exponents was developed by I. Hernandez-Carrasco (Hernandez-Carrasco et al, 2011, Ocean modelling. https://doi.org/10.1016/j.ocemod.2010.12.006).
