Best wishes for 2025, Laurent Soudarin De : Germineaud Cyril Envoy=E9 : mardi 7 janvier 2025 17:42 =C0 : 'OSTST' Objet : [EXTERNAL] [J-3/S6-MF] New Tandem Phase between Jason-3 and Sentine= l-6 MF Dear OSTST community, Happy New Year 2025! Jason-3 will return to a tandem phase with Sentinel-6 MF during 4 months in= 2025, as requested by OSTST and validated by JSG 4partner. A series of orb= ital maneuvers will be performed beginning on January 7, 2025, for about 3 = weeks to allow Jason-3 to reach the orbit of Sentinel-6 MF and fly behind i= t with a one minute delay. Note that no (O/I)GDR products will be produced = during this time. Nominal production of Jason-3 (O/I)GDR products is schedu= led to resume late January with the GDR-01 standard. Distribution will foll= ow in February after necessary CalVal analysis. Please note that the GDR-G standard (see attached release note), presented = at the 30 Years of Progress in Radar Altimetry Symposium in Montpellier (Fr= ance) last year, improves sea level retrievals and ensures better consisten= cy between altimetry missions. This standard will be shared with Sentinel-3= and Sentinel-6 to achieve the best scientific data processing algorithms a= vailable. Best Regards, Cyril on behalf of the Jason-3 Project Team
