ADT - Absolute Dynamic Topography

Abstract: Contents: along-track sea surface heights above geoid; dynamic topography is
the sum of sea level anomaly (SLA) and mean dynamic topography (MDT, Rio05

Use: study of the general circulation (ocean gyres ...)

The data are global mono altimeter satellite products, homogeneous with other
satellites, available in near-real time and in delayed time in NetCDF format.

In delayed time, two types ... View entire text

Ssalto/Duacs products use Jason-1, Envisat, GFO, ERS-1, ERS-2 and
Topex/Poseidon data. File format is NetCDF, but the system also delivers images
in Postscript format (only for gridded products).

Ssalto/Duacs system delivers global and specific regional products; combined
