Topic: Jason-3 Data Gaps
Date/Time Issued: July 12, 2025 1554Z
Product(s) or Data Impacted: Jason-3 Operational Geophysical Data Records (OGDRs)
Date/Time of Initial Impact: July 9, 2025 ~1919Z
Date/Time of Expected End: July 11, 2025 ~2030Z
Length of Event: ~48 hours
Details/Specifics of Change: Due to issues with the NOAA Jason Ground System (NJGS), starting at approximately 1919Z on 9 July 2025, ESPC has been unable to produce OGDRs. EUMETSAT was put in Emergency Backup Mode (EBM) at approximately 2030Z on 11 July 2025 and has temporarily taken over all Jason-3 OGDR processing. As a result there are large gaps in OGDR coverage for the intervening period. The problem with the NJGS is expected to be corrected on 14 July 2025. NOAA will attempt to process the missing OGDRs at that time. We apologize for any inconvenience that may have resulted during this time period.
