Mesoscale Eddy Trajectory Atlas META4.0exp Delayed-Time all satellites

This dataset is composed of the eddy networks and all associated parameters for the eddies detected with the py-eddy-tracker algorithm (Mason et al., 2014. DOI:10.1175/JTECH-D-14-00019.1) freely released under a GPL V3 license (https://github.com/AntSimi/py-eddy-tracker). The detection is made on maps of Absolute Dynamic Topography (ADT) computed with the maximum altimeter satellites available, the maps are distributed by the Copernicus Marine Service (https://marine.copernicus.eu, cf user manual for details). The maps are high-pass filtered with a half-power cutoff wavelenght of 700 km. The amplitude must be over 0.4 cm , the minimum number of grid points within a contour is 5 and the shape error must be below 70% on the raw effective contour. Note that the contour storage resampling may slightly change the provided shape error. The tracking is made through the overlap of the eddies. Networks are divided into segments composed of consecutive eddy observations, linked throught splitting (on eddy split in two or more eddies) and merging (two or more eddies merge in one eddy) events.
