SLA - Sea Level Anomalies

[ Get Data ]

Abstract: Contents: along-track sea surface heights computed with respect to a seven-year

Use: study of ocean variability (mesoscale circulation, seasonal variation, El
NiƱo...), including operational oceanography (near-real time products)

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

Access Constraints Access to Ssalto/Duacs products

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
