- One year into the ESA Digital Twin (DT) Earth Ice Sheets project ❄️@eo4cryo.bsky.social and @tabea-rettelbach.bsky.social with other @esa.int DTs at the science meeting in Frascati to present the pre-operational dtc-ice-sheets.org & new ideas for holistic data cubes 🛰️🌐 #DigitalTwinEarth #IceSheets
- 🍾🥂One of our most exciting pieces of news this month must be the hand-in of Anna Puggaard's PhD thesis on "Earth observation for surface mass balance" on January 15, celebrated with cake and bubbles! We look forward to seeing her in the office as a postdoc in February, after a well-deserved break! 🏝️
- New paper hot off the press in #IEEE JSTARS from our very own @kirkscanlan.bsky.social rkscanlan.bsky.social and @eo4cryo.bsky.social along with @anja-ruti.bsky.social l from #GEUS 🔥🔥 Find it here ieeexplore.ieee.org/document/113...
- 📢 Going to #EGU26? Do you work with #radars on icy and rocky surfaces? ➡️Look no further! Submit an abstract to this session, convened by our @kirkscanlan.bsky.social and @reneefredensborg.bsky.social with Hameed Moqadam! The deadline is fast approaching ⌛ - submit by 15 January 2026 at 13:00 CET!
- Great to be at the 2026 Greenland Ice Sheet Seminar at the Niels Bohr Institute with cryosphere colleagues. Photo: @kirkscanlan.bsky.social presenting for DTU Space. #GreenlandIceSheet #Cryosphere #DTUSpace
- 🌟Meet our Group🌟 @mikkelaabykruse.bsky.social is a PhD student in the Cryo Group. He uses satellite remote sensing to study lakes hidden beneath the Greenland Ice Sheet 🛰️🧊🌊 Some of these lakes can contain and later release enormous amounts of meltwater. #Cryosphere #RemoteSensing #Greenland

- 🌟Meet our Group🌟 Sebastian B. Simonsen (@eo4cryo.bsky.social) is a senior researcher using satellite altimetry to study ice sheets, sea-level change, snow, and ice dynamics. Lately focused on data-driven models and digital twins. PI for Digital Twin Ice Sheets. Also involved in C3S and CCI.
- Our colleague @tabea-rettelbach.bsky.social is developing dynamic data cubes for #EO data over ice sheets (literally 🧊). The goal is to make complex geospatial datasets easier to find, access, and use for e.g. modelers. #datacubes @icelink-project.bsky.social #PISCO #DTC_icesheets
- We have provided new Greenland Ice Sheet mass loss estimates to @polarportal.bsky.social. These are derived from the #GRACE and #GRACE-FO missions, and show that since the launch of GRACE in 2002, the ice sheet has lost approximately 5200 gigatonnes of ice!

- It may be difficult for the untrained eye to see - but we were of course dressed in the colors of glaciers at last weeks Christmas party at DTU Space🧊❄️🎄
- Rasmus and @tabea-rettelbach.bsky.social are in Budapest this week at HungaroMet for the PISCO & @polarres.bsky.social hackathon! 🇭🇺 With 20 other students and instructors, they’re exploring projects that combine climate model outputs with in-situ and EO data to better understand our Polar regions.🌍❄️
- Last week we attended DTU Project Day and had great conversations with many interested students about potential new projects 🛰️❄️ #DTU #ProjectDay #StudentProjects #Research #Cryosphere #RemoteSensing #IceSheets
- We’re attending the IGS Nordic Branch Meeting 2025 in Copenhagen, at GEUS. Great to meet colleagues, hear exciting talks, and spark new discussions on ice, climate and modelling ❄️🧊📊 #Cryosphere #Glaciology #ClimateScience #IceSheet #PolarResearch #NordicScience #IGS2025
- DTU Space was at the Danish Climate Science Symposium 2025 🇩🇰 We’re shared a handful of posters and a talk by Sebastian B. Simonsen: “From Satellites to Digital Twins – Monitoring the Greenland Ice Sheet.” Great discussions on climate, ice, and models! ❄️ #DTUSpace #Greenland #Cryosphere #DMI

- 📢 New publication! Ahead of #ESA #CRISTAL, we explore dual-frequency #altimetry for estimating 🧊 snow depth over sea ice. 🛩️ Part 1: Airborne multi-freq altimetry → snow depth 👉 tc.copernicus.org/articles/19/... 🛰️ Part 2: Compare w/ CryoSat-2 & ICESat-2 #CRYO2ICE 👉 tc.copernicus.org/articles/19/...
- We are proud to be contributors to a chapter on Arctic land ice and its changes in the #AMAP Assessment Report 2026!❄️ #AMAP (Arctic Monitoring and Assessment Programme) is the working group under the #ArcticCouncil that produces science-based assessments to inform policy and decision-making ❄️
- Antarctica is undergoing “greenlandification,” with ice loss processes mirroring Greenland ❄️🌍 New paper out in Nature Geoscience with DTU Space contributions on key signs: doi.org/10.1038/s415... #ClimateChange #Antarctica #Greenlandification
- 🌍✨Great energy at DTU Space with a visit from Unge GIS Brugere! Yesterday, we welcomed GIS users to #DTUSpace. The visit focused on spatial data from #EarthObservations and methods for tackling geospatial challenges, highlighting the importance of precise geospatial data in the Arctic and beyond 🌍❄️
- Last week, @reneefredensborg.bsky.social, Kristina Belinska and Stine Rose enjoyed the Mediterranean sun ☀️ in Crete while presenting results from @esa.int projects #S3MPC #St3tART-FO #IN-PROVA #CCI on calibration and validation of satellite altimetry during the calval4altcrete2025.eu ➡️
- Congratulations to Behzad Forouzi Feshalami for defending his PhD thesis: "Numerical modeling of wave-induced erosion of floating icebergs" - a valuable contribution to improving our understanding of ice–ocean interactions! 🌊🧊 In collaboration with #NTNU, supervised by @spacehsk.bsky.social 🎓
- Last week, @eo4cryo.bsky.social and @spacehsk.bsky.social were in Iceland and NE Greenland on an airborne #FieldCampaign sampling key data over #SeaIce and #LandIce with a brand-new instrument #CRISTALair🛩 Cutting-edge science in action, unlocking insights for future satellites🛰 #EarthObservation

- Three new papers co-authored by @tabea-rettelbach.bsky.social have just been published! A little outside of our usual focus on the cryosphere, as these studies span broader Arctic remote sensing applications: aerial imagery 🛩️, methane emissions🫧, driftwood 🪵. Details and links in the comments ⬇️
- These past three days, @reneefredensborg.bsky.social, @tabea-rettelbach.bsky.social & @kirkscanlan.bsky.social participated in the Symposium on Technology Advancement for Ice Remote Sensing (STAIRS) in Copenhagen, organised by the University of Copenhagen and the University of Manitoba 🛰️❄️
- Welcome to our new bachelor students! 🎓 Yesterday marked the start of the new study year at DTU, where we welcomed 42 new bachelor students to our Earth and Space Physics and Engineering programme. Our head of study Sine Hvidegaard made sure the students got a good intro to their new student life.
- Congratulations to DJ Upside Down Turtle and DJ Disco Disc for their triumph in the inaugural Cryosphere Group Disc Golf Championship! 🥳🥳 A lovely afternoon spent with great colleagues and only "a few" discs had to be dug out of trees or fished out of water. Time to start practicing for next year 🙃
- 📢 A new study pinpointing 📌 differences in RCM melt extent using observations from ASCAT 🛰️ is out! Led by our PhD student Anna Puggaard with @louisesandbergs.bsky.social, @eo4cryo.bsky.social and colleagues from @dmidk.bsky.social, GEUS and ENVEO. Interested? See ➡️ tc.copernicus.org/articles/19/...
- Exciting news from our team to start the weekend! 🎉Our own eo4cryo.bsky.social has joined the Strategic Advisory Board for the EU’s #DestinationEarth initiative 🌍 Read more about the expectations for the initiative and @eo4cryo.bsky.social's role here: www.dtu.dk/english/news...

- 📢Just before a busy summer, a new paper dropped by our very own @kirkscanlan.bsky.social and @eo4cryo.bsky.social with @anja-ruti.bsky.social and our friend Nicolaj Hansen from @dmidk.bsky.social ➡️ doi.org/10.1038/s415...

- We have contributed to this interesting paper, which has been published today: 🧊 It shows a rare subglacial flood in Greenland, where water forced its way upward through the ice sheet. 📡 Satellite data revealed this event was triggered by rapid drainage of a hidden lake beneath the ice .
