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
datasets are also provided for high precision altimetry.
Near-Real Time products cover the 2001/08/22 - 2006/11/14 period. Delayed time
data are available from October 1992.
Condition of access
Ssalto/Duacs NRTNear Real Time data are available via FTP:
- with user identification and password for data <1 month , for scientific
applications (GodaeGlobal Ocean Data Assimilation Experiment, seasonal/climate
prediction centers) provided that a data use agreement is signed with Cnes.
- or freely available for data older than one month (i.e NRT and DT data> 1
month)
CLS remains in charge of the commercial applications of these near-real time
products.
Acknowledgements
For both DT and NRT products, the above acknowledgement has to be cited: "The
altimeter products were produced by Ssalto/Duacs and distributed by Aviso with
support from Cnes".
See http://www.aviso.oceanobs.com/html/donnees/duacs/access_uk.html for
additional details.
When using Ssalto/Duacs data (NRT or DT-(M)SLA and (M)ADT), please cite: "The
altimeter products were produced by Ssalto/Duacs and distributed by Aviso, with

NetCDF
Contents: along-track sea surface heights above geoid; dynamic topography is
the sum of sea level anomaly (SLA) and mean dynamic topography (MDT, Rio05
here)
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 of products are available:
- "Ref" (Reference) series: homogeneous datasets based on two satellites
(Topex/Poseidon, Jason-1 + ERS, Envisat) with the same groundtrack. Sampling is
stable in time.
- "Upd" (Updated) series: up-to-date datasets with up to four satellites at a
given time (adding GFO and/or Topex/Poseidon on its new orbit). Sampling and
Long Wavelength Errors determination are improved, but quality of the series is
not homogeneous.
Regional products with an improved quality are available in local areas
