The dynamic interpolation method (Ubelmann et al., 2015) has recently been applied to real along-track data to produce high-resolution gridded maps in regional configurations (Gulf-Stream, Mediterranean, ACC,…). A serie of validations and comparisons against independent data have been conducted to assess the performances with respect to the reference CMEMS gridded maps. If it is sometimes a challenge to outperform in low-energy areas, we found that the mesoscale of instense jets can be significantly improved, revealing new eddies and smoother trajectories. We propose here to present these configurations and validations. Beyond the Gulf-Stream configuration, a serie of regional products will be developed soon to be available on Aviso.
