Eddy trajectory Atlas products: updates and reprocessing

September 2020: extension of the DT2.0exp META 

Please find an extension of the META2.0exp DT eddy trajectory product until 2019/10/15.

Please find below the format/information changes compared to former delivery (released in June 2019):

  • Although the eddies and trajectories are the same in the former and current versions, the trajectory indexes have changed. The eddies and trajectories can be found with their time and spatial characteristics which remain unchanged.
  • The extension of longitudes : formerly between 0-360°E, and now some of them are <0°E or >360°E in order to have a continuity for the trajectories which cross the Greenwich Meridian in one direction or another.
  • Changes in the attributes of some variables, with no impact on the variables content.
  • The units of amplitude, speed_radius and speed_average which are now in SI units.
  • The variables integrated in the netcdf are now stored with a scale_factor (transparent for users when data is loaded).

This dataset is experimental, so all feedbacks are welcome ( to help us understand how this product is used by the community, and to improve the algorithm, production and validation processes.

All the information about this atlas can be found in the product page
