Description: eddies detected from the multimission altimetry datasets, with location each day giving the type (cyclonic/anticyclonic), speed, radius and associated metadata, in delayed-time (version DT2.0exp) for the whole altimetry period: 1993-ongoing, and in near-real-time (version NRT3.0exp) for: 2018/01/01-15 days delay
Geographic coverage: global
Format: NetCDF-4 Classic with CF standards.
