Ssalto/Duacs multimission altimeter products
Duacs is the Ssalto multimission altimeter data processing system. It serves in near-real time the main operational oceanography and climate forecasting centers in Europe and worldwide.
Ssalto/Duacs system processes data from all altimeter missions (Jason-1&2, T/P, Envisat, GFO, ERS-1 & 2 and even Geosat) to provide a consistent and homogeneous catalogue of products for varied applications, both for near real time applications and offline studies. Ssalto/Duacs Near-Real Time data are used, in particular, by Godae and its French contribution Mercator Océan. In delayed time, hundreds of teams retrieve historical Duacs datasets.

1st August 2012: Version 13.2.0 of SSALTO/Duacs: new altimetric standard version "D"
Altimetric data are regularly reprocessed in order to take into account new algorithms, corrections, parameters, etc. Since its launch in June 2008, Jason -2 products have been disseminated in version "C". For Jason -2, it is now time to change for another standard to benefit from many years of progress in altimetry.
Main differences between versions "C" and "D" are described in the links below.
