MTG-I1, now called Meteosat-12, has become in June the prime geostationary satellite in 0°. EUMETSAT OSI SAF is now proud to distribute the Sea Surface Temperature derived from MTG data. @eumetsat.int @eumetsat-users.bsky.social

Disregarding the extreme and record-low sea-ice extent in Antarctic the last two years, this year's July extent is exceptionally low, ranking as the 3rd lowest on record. The July extent over the last four years differs significantly from that of the previous four decades. @osi-saf.eumetsat.int

In July 2025, the #SeaIce global extent was 8.9% below 1991-2020 mean. Since the beginning of records (1978): - #Arctic, 4th lowest monthly mean, with 9.9% less extent (-906.931 km²) - #Antarctic, 3rd lowest monthly mean, 8.3% less exent (-1.363.243 km²) For more: osisaf-hl.met.no/v2p2-sea-ice...

The EUMETSAT Climate Symposium is from 28–30 October 2025. The event will take place at darmstadtium Science and Congress Center in the heart of Darmstadt, Germany, 30km south of Frankfurt. Register now to join us & celebrate 25 years of Climate@EUMETSAT: www.eventsforce.net/eumetsat/fro...

#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. more on: osi-saf.eumetsat.int/community/li... #climate #arctic #antarctic

How do we at @osi-saf.eumetsat.int prepare the Sea-Ice Index for the potential End-of-Life of SSMIS after July? 1. Compute indexes from AMSR-2 instead 2. Develop a calibration tuned over 2021-2025 3. Continue the index time series with calibrated AMSR-based indexes from August 2025. 👉 (link below)

A large polynya has developed northeast of Greenland. This is clearly visible in the new AMSR-based sea-ice concentration product (OSI-438), but is less visible in the SSMIS-based product (OSI-430) due to its lower spatial resolution. 🧪🌊🥼❄️

If you wonder what difference are between our AMSR-2 based and our SSMIS based Sea Ice concentration products, check this post from @signeaaboe.bsky.social

Come and meet our team at @eumetsat.int satellite conference in Lyon!

MTG-S1 is on its way to geostationary orbit! 🚀 Launched on 1 Jul the satellite is now undergoing a complex 17-day journey to reach its new home 36,000km above Earth. Julia Hunter-Anderson shares how her team's guiding it through space from Telespazio Mission Control Centre. Read more: bit.ly/3IH6Edn

ICYMI: Our Lead Marine Expert Hayley Evers-King spoke at #UNOC in June about what ocean colour tells us - from water quality to #ClimateChange. 🌊🛰️ DYK satellites like Sentinel-3 help us spot the good, the bad, and the ugly from space? Watch here: bit.ly/4606uYy

⚠️Deadline extended to Friday 11 July! A limited amount of financial support is available to help participants join us, celebrate 25 years of Climate@EUMETSAT and shape the future of climate services. Applications for support can be made during registration: www.eventsforce.net/eumetsat/fro...

📣 Note - Are you using sea-ice concentration climate data from OSI SAF, please be aware that an AMSR-2-based product is now being released to replace the SSMIS-based product (soon end-of-life) 👉

🛰️New Product ! 🛰️ Our #SeaIce team at @met.no and @dmidk.bsky.social has been working hard to ensure you reliable and lasting access to sea ice concentration Climate Data Record. Today we release as demonstrational a new #AMSR-2 based Interim CDR (OSI-438) osi-saf.eumetsat.int/community/li...

If you are using our climate data and wish to learn more about the satellite climate data available, join @eumetsat.int Climate symposium next October!

WHAT...A...LAUNCH! 🚀 We're thrilled at yesterday's successful MTG-S1 & Copernicus Sentinel-4 launch, a huge congrats to all teams & partners involved 👏 MTG-S1 will deliver vital atmospheric data for earlier, more accurate warnings - helping protect lives & infrastructure. 📷 Images by SpaceX

🔴 NOW LIVE! Launch coverage of the second of the Meteosat Third Generation satellites and the first instrument for the Copernicus Sentinel-4 mission. Watch live on esawebtv.esa.int. 🚀 Liftoff with SpaceX on Falcon 9 is expected at 23:03 CEST.

Live in 1️⃣ hour! Join us for a front-row seat to the MTG-S1 story 15 years in the making. The satellite is now ready with Falcon 9 on the pad for launch. 🚀 Want to join in the fun? Use #MTGS1 - your msg could appear on our in-house social wall 📽️ ESA/SpaceX

🚧 The US #DMPS notified us yesterday that the #SSMIS data would still be distributed for another month, until 31/07/2025. We still strongly invite our SSMIS #SeaIce only products users to switch to our #AMSR-2 based products. For more information: osi-saf.eumetsat.int/community/st...

Today is again an important day for our #seaice community, as #JAXA is about to launch #GOSAT-W. Aboard this satellite is the passive microwave radiometer #AMSR-3 that will provide us with key data for our sea-ice products. がんばって JAXA ! Launch is due at 16:33 UTC universeodon.com/@revesdespac...

🚧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 30/06/2025. Consequently, we advise SSMIS only-based #SeaIce products users to urgently change. More information: osi-saf.eumetsat.int/community/st...

One can meet a lot of people in #LPS25 : here a random meeting between Stewart Turner, the EUMETSAT Member States representative in our Steering Group and @gwenbras.bsky.social, our communication officer in front of a #Sentinel-6 model. Look for us, and you'll meet us!

🛰️Are you planning to attend the #LPS25? 🌎 Our project team will be represented in Vienna. Make sure to meet us at the @eumetsat.int booth !

🚧 Access to SSMIS data from the US #DMSP satellites is becoming less reliable as this satellite program is reaching its end. Data will become scarser with the time until a full stop in 09/2026. Several OSI SAF #SeaIce products are affected. More information: osi-saf.eumetsat.int/community/st...

Our sea surface temperature (#SST) team is taking actively part to the @ghrsst.bsky.social #GHRSST26 meeting! We're working on designing the future of our products together with the worlwide SST retrieval community!
