  1. Following #SSMIS impredictable data provision, in order to ensure our users with a reliable service, we are now basing our Sea Ice Index on AMSR-2-based Sea Ice Concentration product.

  2. #SSMIS data-end grows close.

    Our #SeaIce team has been busy this summer to ensure product continuity.

    Our Sea Ice Index will be updated from v2.2 (SSMIS based) to v2.3 ( #AMSR2 based) from Friday 01/08/2025 on, but access to it will remain unchanged, ensuring a straightforward transition.

  3. Ab dem 31. Juli soll die US-Wetterbehörde #NOAA keinen Zugang mehr zu wichtigen #Satellitendaten für die #Hurrikanvorhersage erhalten.

    Die #Trump-Regierung unterstützt den Schritt des #Verteidigungsministerium​s, das die Daten aus #Sicherheitsgründe​n nicht mehr teilen will.

    Fachleute warnen vor sinkender #Vorhersagegenauigkeit. Besonders betroffen ist das 3D-Radarbildsystem #SSMIS, das Stärken und Veränderungen von #Wirbelstürme​n früh sichtbar macht.

  7. 🚧 The US #DMPS notified us yesterday that the #SSMIS data would still be distributed for another month, and be extended to (no later than) 31/07/2025. We still strongly invite our SSMIS #SeaIce only products users to switch to our #AMSR-2 based products.

  12. Turning off the vital data stream from a perfectly good healthy satellite is just mind boggling. And I'm supposed to still be on leave FFS #SSMIS

  13. The loss of the #SSMIS satellite dataset as warned by @osi_saf will presumably also affect the #Greenland today melt maps over on NSIDC - I think we have AMSR2 for those somewhere too, but not exactly sure where..

    Perhaps I should write that blog post I was talking abotu earlier 🤔

  14. While I started on some vacations in #France, the #SeaIce teams at @osi_saf work hard to minimise the impact of the sudden loss of US #SSMIS data for our users. We got the news yesterday that the data flux will stop already on Monday June 30th!

  15. 🚧Urgent notice to all SSMIS product users 🚧

    We've just been informed that #SSMIS from the US #DMSP satellite will stop to be distributed on Monday 30th June 2025.

    Consequently, we advise SSMIS only-based #SeaIce products users to urgently change.

  16. @sthendric . @osi_saf sent a service message to all our users about the situation with #SSMIS

    We will keep our users updated as things evolve through service messages, and here:

  17. @phil_browne Good morning Phil.

    This method is used only for OSI-450-a, the v3 Climate Data Record (1978-2020).

    We don't need it for the associated Interim CDR OSI-430-a (2021-onwards) because the ICDR uses #SSMIS only, and those missions have a small polar observation hole: it does not matter how we interpolate.

    The new method was not used in our "v2" data (OSI-450 and OSI-430-b): we were using the isotropic interpolation even for the #SMMR period (which our users complained about).

  18. @kevpluck @ZLabe @SigneAaboe @AlaskaWx Some #SSMIS data eventually came during the (European) night and since there are three satellites, it seems we could produce nominal #SeaIce products (on time, no data hole).

  19. We are still not receiving data from the DMSP #satellites F16, F17, and F18.

    These three satellites carry the #SSMIS instrument that #OSISAF and #NSIDC use for their #SeaIce climate monitoring.

    The issue is apparently related to power outage on the ground segment: ospo.noaa.gov/data/messages/20

    Expect delays and/or data gaps in some upcoming #SeaIce products.

    fyi @ZLabe @kevpluck @SigneAaboe @AlaskaWx

  20. @kevpluck @AlaskaWx Good.

    I think #nsidc has some temporal interpolation going (we do that at #osisaf).

    We did not manage to retrieve #SSMIS data for the 9th (lost for good?). As a result, our sea-ice index shows an "interpolation" flag for that day.

  21. Wooohoooo ! We are now receiving data from the #SSMIS F16, F17, and F18 satellite missions !

    #osisaf and #nsidc will thus soon resume their #seaice extent processing.

    @AlaskaWx @zlabe @kevpluck

  22. Update on the #SSMIS data shortage (that prevents us to update our #osisaf #seaice extent timeseries) ...

    "Problem with planned maintenance caused a rack to go down affecting systems in it. Technicians working to bring rack up and recover data."

    So still #nodata, but confirmation that the satellites are doing fine.

    Oh well... we'll wait.
