80 000! Phwoar!

On 12 May, our ice mission made 80 000 orbits of our pale blue dot 🤩

15 years, 80 000 orbits, and still going strong.

Here's to many more for CryoSat!

15 years monitoring Earth's cryosphere, oceans, rivers, lakes...and much more! Thank you, @esa_cryosat for enabling amazing discoveries!!! 🩵🧊🛰️✨🎊

[ESA's CryoSat mission @esa_cryosat]

It's our 15th space birthday! 💫🛰️🥳

Fabulous new research shows just why CryoSat is so treasured, using its phenomenal record since 2010 to give us the big picture of how growth, melt & drift contribute to interannual changes in Arctic sea ice 👌

Airborne data from the ESA CryoVEx/DEFIANT Antarctic campaign of 2022/23 is now available on CS2EO!

Time to delve in 👇

Sea ice is fading. But how much?

Although different products agree that sea ice is changing, there is little consensus about precisely how much.

Researchers are invited to delve into a treasure trove of satellite data, including those of @ESA_EO's CryoSat mission, to agree a reconciled estimate of sea ice thickness.

Big news in the world of ice!

On 6 February 2025, the observations of @ESA_EO's CryoSat and @NASA_ICE's ICESat-2 satellites will align almost perfectly with each other, providing the best opportunity yet to measure sea ice, snow & polar ocean currents from space 🧊❄️🌊

The news you've all been waiting for...

‼️ The full programme for the 12th international workshop on sea ice modelling, assimilation, observations, predictions, and verification (IICWG-DA-12), is now live!

@esa_swarm @GuramNK Way to go @esa_swarm ! Keep us posted about new results in synergy with your fellow @esa_cryosat 😉

[ESA's CryoSat mission @esa_cryosat]

@AlexDiBella @helenafricker @HSkourup @dr_slfarrell And thanks to this golden team, Matteo, Francesca, Chiara and Kimberly (not here unfortunately!), for putting on a wonderful event.

Let's do another one! 🤝😎

[Dr Sinead L Farrell @dr_slfarrell]

And the future, you ask? What's up next for #PolarAltimetry? It's exciting! We're busy planning for the upcoming @esa #CRISTAL mission, due for launch in 2027/2028. #Cryo2Ice Symposium 2024.

[ESA's CryoSat mission @esa_cryosat]

What a venue! What an event!

#Cryo2ice is almost over, but not quite yet.

Time now to summarise this incredible "family reunion" of our milk and cookies, CryoSat and ICESat-2.

We're about to hear from all our chairs, before a wrap up from @tparrine & @Thorsten_Markus

[ESA's CryoSat mission @esa_cryosat]

@tparrine @NASA_ICE @esaoperations @DenisFelikson @NSIDCDAAC @ESA_EO @AlexDiBella Thanks to all our chairs and speakers!!

Lunch time

[ESA's CryoSat mission @esa_cryosat]

@tparrine @NASA_ICE @esaoperations "The time difference between the measurements is decreasing"

Jan 21 next year we should have quasi-synchronous measurements 🤩

[ESA's CryoSat mission @esa_cryosat]

Javier Sanchez now of @esaoperations tells us about the manoeuvring of CryoSat to align with ICESat-2 over the poles.

We started in the Arctic configuration in 2020, switched to Antarctica in 2022, and switch back to the Arctic in 2025.

A fascinating look at how you manoeuvre a satellite like CryoSat 🤩

[ESA's CryoSat mission @esa_cryosat]

"CryoSat has revolutionised how we measure our planet's cryosphere"

@tparrine opens the session on mission status with a look at our super CryoSat mission!

[Dr Sinead L Farrell @dr_slfarrell]

Are you interested in what exactly #CryoScientists do with #PolarObservations? Thanks to @esa_cryosat here's the answer:

Our gorgeous venue for #Cryo2ice on this gorgeous first morning. Harpa Concert Hall, Reykjavik 👌

[ESA's CryoSat mission @esa_cryosat]

Reasons to be excited about #Cryo2ice, no4...

The Cryo2ice symposium!

Next Monday we'll gather in Reykjavik to share a treasure-trove of research covering glaciers, ice sheets & shelves, sea ice, snow, oceans & more

📊 CryoSat data news 📊

New query history and Time Series Processing features for https://t.co/5a508VEq2V

❓ cs2e0, developed by @earth__wave, now offers a query history and download history, allowing logged-in users to revisit, modify and resubmit past queries, and to retrieve file download links for more recent ones.

🚞 The Time Series Processing tool now allows users to plot percentile bands, showing the spread of elevation change over the selected area, and to apply an outlier removal algorithm to remove spurious data points.

In the golden age of satellite altimetry, we're approaching a golden moment 🌟

In Feb 2025, the orbits of @ESA_EO's #CryoSat and @NASA_Ice's #ICESat2 will be almost simultaneous 🤩

Just one reason to be excited about next week's #Cryo2ice symposium!
