FSLE - Finite-Size Lyapunov Exponents and Orientations of the associated eigenvectors

The maps of Backward-in-time, Finite-Size Lyapunov Exponents (FSLEs) and Orientations of associated eigenvectors are computed over 30-year altimetry period and over global ocean in Delayed-Time and in Near-Real-Time. As a snapshot, each map represents the sea state for a given day. The Exponents and Orientations are distributed on a 1/25deg grid on a global coverage. In Delayed-Time, the maps are calculated every days since 1994/04/01. They are updated every year. In Near-Real-Time, the maps are delivered every day, with 20 days of delay.
