Atlas DYNED of 3D Eddies in the Mediterranean Sea - Temps différé

Other

Eddies detected in Delayed-Time (DT) for the entire period [1993 - present]. Variables provided include day-by-day, and for one rotation type (Cyclonic/Anticyclonic) :

  • Center position (Longitude and latitude of the center of the best fit circle with the contour of maximum circum-average geostrophic speed);
  • Amplitude (|SSH(local_extremum) – SSH(outermost_contour)|);
  • Speed radius (Radius of the best fit circle with the contour of maximum circum-average geostrophic speed);
  • Speed average (Average geostrophic speed of the contour defining the speed radius);
  • Speed profile (Profile speed average values from effective contour inwards to smallest inner contour);
  • Effective contour (Largest contour of the detected eddy);
  • Speed contour (Contour of maximum circum-average geostrophic speed for the detected eddy).

The ”allsatellite” maps (Allsat) are built with all the available satellites at a given time, improving the small scales representation in the maps due to the diversity of the tracks’ location and the different repetition periods of the altimetric missions.
