New release of the Finite-Size Lyapunov Exponents (FSLEs)

Category: Website updates

We are pleased to announce the new release of the AVISO+ dataset Finite-Size Lyapunov Exponents (FSLEs)

The maps of Backward-in-time, Finite-Size Lyapunov Exponents (FSLEs) and Orientations of associated eigenvectors have been updated after a whole reprocessing from January 1st 1994 to January 18th 2018. Data are computed over global ocean within the SALP/Cnes project in collaboration with CLS, LOcean and CTOH.

The main upgrades for this reprocessing are the following:

  • madt_uv input data are derived from DUACS DT2018 instead of DUACS DT2014.
  • Data are available daily from 01-01-1994 to 18-01-2018
  • Initial separation is 0.02 degree instead of 0.04 degree. The filaments are much thinner.

Data format remains unchanged.

More information can be found on the product page

Data are available on FTP and on Gridded Data Extraction tool from : My AVISO+ web page.
