New AVISO products: Lyapunov Exponents and Orientations

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).

Note that these products are devoted to scientific applications and non-commercial use as indicated in the <link http: www.aviso.altimetry.fr fileadmin documents data license_aviso.pdf>licence agreement (issue 7). Please, if you want to use them, fill in the <link internal-link>online form to subscribe to these new products.

All the information is given in the Aviso+ <link http: www.aviso.altimetry.fr en data products value-added-products fsle-finite-size-lyapunov-exponents.html>product page with a  <link http: www.aviso.altimetry.fr en data products value-added-products fsle-finite-size-lyapunov-exponents fsle-description.html>complete description and in the <link http: www.aviso.altimetry.fr fileadmin documents data tools hdbk_fsle.pdf>user handbook. Moreover, a dedicated webpage showing  <link http: www.aviso.altimetry.fr en data products value-added-products fsle-finite-size-lyapunov-exponents fsle-description fsle-examples-of-applications.html>examples of use is available. Do not hesitate to send us your feedbacks and papers, we will be pleased to insert them in this page.
