Project engineer working at @CLS_group on #altimetry sea-ice and ocean, with a slight addiction to all space related things …

I was thrilled to be there 🤩 Great conference… the Northern lights were definitely the cherry on top of the (sea)-iced cake 😁

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_cryosat @AndyShep_CPOM @CPOM_news So beautiful 🤩

@rachel_tilling @NASAGoddard @UofMaryland @DgfiTum @amy_swiggs @CPOM_news @NorthumbriaUni @FannyPiras next of @CLS_group who was up watching the northern lights yesterday!

Now to dazzle us with an inter-comparison between the reprocessed Sentinel-3 sea ice products, Cryosat and IceSat-2 over sea-ice 🌊🧊

Well this time I did not miss it @esa_cryosat 😎 We can even this the conference center in the lower left corner 😁 #Cryo2Ice

[Fanny Piras @FannyPiras]

Arrived in sunny Reykjavik for the #cryo2ice conference 🤩 ☀️🇮🇸Very excited to be here all week and hear all about @esa_cryosat and @NASA_ICESat2 !!

[Fanny Piras @FannyPiras]

Great week ! I was very happy to be able to give 3 talks in different sessions ☺️

🌍 Celebrating 30 Years of Precise Altimetry! 🌊

💡 This year marks the 30th anniversary of precise altimetry, a major milestone in Earth observation. To celebrate, the @esa , in collaboration with our parent company, the French Space Agency (@CNES ), hosted the "30 Years of Progress in Radar Altimetry" symposium this week in Montpellier, France.

👨👩 As a global leader in altimetry, CLS is proud to have 42 of our experts  giving 28 talks and also presenting numerous posters showcasing our expertise in data qualification and sea level products for the international scientific community.

🛰 With over 30 years of experience in processing, calibrating, and validating altimetry data, CLS has developed unique processing chains that provide critical data to scientists, climatologists, oceanographers, biologists, and hydrologists worldwide. These insights help calculate ocean, lake, and river levels, as well as address key environmental challenges like:

📈 Monitoring global Mean Sea Level rise, a key global warming indicator (in partnership with LEGOS and CNES)
💧 Tracking inland water resources, including surface, depth, and flow of water networks.
❄️ Observing ice sheet dynamics and their impacts on sea level rise.
🌊 Identifying areas at risk of coastal flooding.

👏 A huge congratulations to our team for their contributions this week, representing the 120+ dedicated individuals at CLS who work daily to advance these crucial activities. Together, we are turning data into action for the benefit of the planet.

Welcome back to earth ERS-2 🛰️😁

[ESA Operations @esaoperations]

UPDATE 19:30 UTC (20:30) CET

We have confirmation of the atmospheric reentry of ERS-2 at 17:17 UTC (18:17 CET) +/- 1 minute over the North Pacific Ocean between Alaska and Hawaii.

With @ESA_EO I am exploiting data from historical missions ERS-1, ERS-2 and ENVISAT in the frame of the #FDR4ALT project. Today is a bit special because ERS-2 is coming back to Earth ! I believe it is not something I will see very often in my carreer !

(2/2) So 98% reduction ! Actually proud to be in a team that is ready to change their habits 💪
Thanks also to @ESA_fr and @eumetsat because the conference started on a Tuesday which is way more practical to take the train.

[Fanny Piras @FannyPiras]

(1/2)Last week I was at the #S3VT in Darmstadt, Germany. From @CLS_Group , we were 9 people to take the train 😍 My collègue Victor Quet decided to look at the impact in terms of CO2 emissions :
✈️ —> 4.5T CO2eq
🚆 —> 0.0635 T C02eq

[Fanny Piras @FannyPiras]

@EmmaWoolliams @jdpereira @EeroRinne I remember this one quite well 😁 And of course it is totally accepted that we manage the agenda in a way that parents can go and get their kids. It is common sense to me 👍

[Fanny Piras @FannyPiras]

Arrived in #Darmstadt for the Sentinel-3 validation team meeting. We will present the excellent performances on the sea-ice reprocessed products ☺️ @ESA_EO @CLS_Group

Finally !! 🤩

Finally out! Sea ice freeboard from ERS-2!

[Prof. Eliot Jacobson @EliotJacobson]

Everything is happening.

While climate scientists have been talking about North Atlantic sea surface temperatures these last few days, what's going on with sea ice in Antarctica is even more extreme, nearly 2.4 million km² below the 1991-2020 mean, with a big jump down today.

[Fanny Piras @FannyPiras]

Memory from last night at the great #IGSSeaIce dinner … I was really thrilled to meet so many people from the sea-ice community. I learned so much ! Hopefully we’ll meet again soon ! Bye Bremerhaven ✌️

[Fanny Piras @FannyPiras]

@EmmaWoolliams @igsoc Have a safe journey ! I’m leaving tomorrow around 14:00 so I guess that we won’t cross paths. Enjoy the workshop, I’ll be interested to read any feedback ☺️
