Operational news about Ssalto and Duacs processing system.

11.09.2008 Ssalto/Duacs products updated

After the problem detected on Jason-1 the 2008/08/07, Jason-2 data was integrated in Ssalto/Duacs near-real time processing.

In order to consolidate the quality of Duacs data over the past weeks,  the data were reprocessed (between the 2008/08/07 - 2008/08/29 for the gridded products and between the 2008/08/07 - 2008/09/02 for the along track products). The regional product on the Mediterranean Sea (regional-mfstep) is also concerned for the gridded and along track data. Today, all is nominal.

25.08.2008 SSALTO/DUACS products unavailable since 2008/08/21

The recent Jason-1 safehold mode induced a data gap in the Jason-1 altimeter data series and this gap is larger than the one allowed by the resilience of the DUACS system.

The production is scheduled to be resumed this night.
