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...

This was a super fun and challenging project to work on, trying to synthesise measurements from three different satellites 🛰️🛰️🛰️ over 10 years 🗓️ to make never-before-attempted observations. Big thanks to the @esaearth.esa.int Living Planet Fellowship for supporting this work 👏

In the paper we combine data from #ESA CryoSat-2 #ISRO/#CNES SARAL/AltiKa and #ESA SMOS to showcase how vertical density heterogeneity across the ice sheet changes through time and space. The firn layer plays a critical role storing meltwater and buffering sea level rise 🧊🌊

Heading to #EGU26 and use #radar to study terrestrial and planetary surfaces (both icy and rocky 🤯)? Have we got the session for you!

Consider submitting an abstract to #EGU26 CR6.3 by January 15 2026.

Read more about the session here www.egu26.eu/session/56853

Hope to see you there!

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🧊❄️🎄

Brand new website for the Cryo Group at DTU is now live! Thanks to @reneefredensborg.bsky.social for making us look so good 🤪

The winners!!

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 🙃

Exclusive: retraction-prone editors identified at megajournal PLoS ONE Study says small editor group handled many problematic manuscripts — and a Nature investigation finds out who they are.

What a bonkers story 🤯

A big thanks to the @villumfonden.bsky.social Experiment Program and the @esaearth.esa.int Living Planet Fellowship Program for supporting this work!

@anja-ruti.bsky.social @eo4cryo.bsky.social and our colleague Nicolaj from @dmidk.bsky.social did this by looking at how strongly radar signals bounced off the surface of the ice sheet. We then validated our results using a bunch of in situ measurements and compared against state-of-the-art models.

Novel insight into the spatiotemporal distribution of Greenland ice sheet surface densities from eleven years of satellite radar altimetry - Scientific Reports Scientific Reports - Novel insight into the spatiotemporal distribution of Greenland ice sheet surface densities from eleven years of satellite radar altimetry

And why not one more while we're at it. Have you ever wondered how surface conditions across #Greenland change with time? Us too! Here we recovered 11 years of "surface" density changes from satellite altimetry. A whole new window into how Greenland is changing. doi.org/10.1038/s415...

Greenland Ice Sheet surface roughness from Ku- and Ka-band radar altimetry surface echo strengths Abstract. Surface roughness is an important factor to consider when modelling mass changes at the Greenland Ice Sheet (GrIS) surface (i.e., surface mass balance, SMB). This is because it can have impo...

Better late than never. Big thanks to @anja-ruti.bsky.social and @eo4cryo.bsky.social for all their help as we try to unravel #Greenland Ice Sheet surface roughness from radar altimetry. Hat tip to the @esa.int Living Planet Fellowship program for supporting this work! doi.org/10.5194/tc-1...
