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.

Release of sea ice index product version v2.3 | OSI SAF

We are now releasing version 2.3 of the OSI SAF Sea Ice Index product. As previously announced (service messages #3328 and #3329), the Sea Ice Index product (OSI-420) will in the future be calculated from the AMSR-2-based Sea Ice Concentration product (OSI-438) instead of the SSMIS-based concentration product (OSI-430-a). Note that sea-ice index values up until July 31, 2025, are identical in versions 2.2 and 2.3. Only index values from August 1, 2025, and onward will be affected by this data input change.

#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.

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 #Verteidigungsministeriums, das die Daten aus #Sicherheitsgründen nicht mehr teilen will.

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

Trump admin will cut hurricane forecasters out of key satellite data in one month

The Defense Department will still maintain the satellite program will cease sharing the imagery with NOAA and NASA.

🚧 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.

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

Loss of #SSMIS satellite as warned by @osi-saf.eumetsat.int will presumably also affect the #Greenland today melt maps over on NSIDC - I think AMSR2 melt maps exist for that but not sure where Perhaps I should write that blog post I was talking about earlier 🤔 osi-saf.eumetsat.int/community/st...

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 🤔

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!
