  1. Introduction of X-track processor and products Validation of x-track SSH 1Hz product for CalVal applications X-track, a new processing tool for altimetry in coastal areasL. ROBLOU, G. JAN, J. LAMOUROUX Jason-1 pass 222 M3 tide gauge (Senetosa) Mean=0.1046m Std dev=0,0252m SSH absolute bias at M3 tide gauge, Jason-1 pass 085 Jason-1 pass 085 Applied to : GOCEAN Project * ALTICORE Project (Poster at Hobart OSTST) Le Hénaff studies (Gulf of Bisay) * Maraldi studies (Kerguelen) (Poster at Hobart OSTST)

  2. Suggestion of a common exercise for in situ CalVal and data consistencyG.Jan (1), Y. Ménard (2), P. Bonnefond (3), O. Laurain (3), L. Roblou (1)(1) NOVELTIS (2) CNES (3) OCA • Proposal to compare and synthesize sea surface height (ssh) bias results from in situ CalVal methods. • To analyse the results from CalVal sites on a computing basis as comparable as possible • Nothing new. But, the exercise could give a common framework for ssh bias computing with conditions as homogeneous as possible. This exchange plan would be made with the participantCalVal teams. It would be proposed to be applied before OSTST future meetings.

  3. Proposal of exercise to compare and synthesize sea surface height (ssh) bias results from in situ CalVal methods. To analyse the results from CalVal sites on a computing basis as comparable as possible Suggestion of a common exercise for in situ CalVal and data consistencyG.Jan (1), Y. Ménard (2), P. Bonnefond (3), O. Laurain (3), L. Roblou (1)(1) NOVELTIS (2) CNES (3) OCA • It requires: from the different works on in situ CalVal missions. • The definition of a common protocol to compute ssh bias (epoch, corrections choices) • The implementation and realization of the CalVal exercise for participant teams. • Results analyses
