Category: Website updates

The Aviso Team is pleased to announce the release of new products: Finite-Size Lyapunov Exponents (FSLEs) and Orientations of associated eigenvectors. The FSLEs are computed over 21 years and over global ocean within the SALP/Cnes project in collaboration with CLS, LOcean and CTOH. They provide the exponential rate of separation of particles trajectories initialized nearby and advected by altimetry velocities.

Those products can be used for studies on the ocean variability in different domains of biology, assimilation, societal applications,.... Those high level products are gridded (1/25°) and cover the global ocean and provided in Delayed-Time (every 4 days from 1994/01/04 to 2014/10/22).
