📢 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/...
9/ You can learn more about the #Cryo2Ice Campaign which realigned #ESA 's #Cryosat2 to have better coincidence to #NASA's #ICESat2 which made this study possible: t.co/F4jKH64ooa
3/ 🔍 Our study is the first to assess snow depth retrieval using #Cryo2Ice data in a leadless region. Without leads to estimate sea surface height, we developed a method using ellipsoidal height differences between the satellites and accounting for tides.
1/ 📢 Excited to share our new research published in #TheCryosphere on snow depth estimation in the Canadian Arctic Archipelago using #Cryo2Ice satellite data! 🛰️ Here's a thread on what we found and why it matters. 🧵👇

Last week I had the opportunity to present our latest research to the ice altimetry community at the #CRYO2ICE symposium. I talked about AWI-ICENet1, our new AI-based retracking algorithm for ice altimetry (doi.org/10.5194/tc-1...). I took home fantastic feedback and a lot to think about.
Satellite altimetry as a way to directly measure the height of Earth’s surface from space started in the 1970s, and has evolved through distinct eras. At Cryo2ice I highlighted what these data have taught us about Antarctic mass loss and the driving processes. #ErasTour #Cryo2ice
Final wrap-up session of #cryo2ice in Reykjavik. What an amazing meeting this has been bringing together the CryoSat-2 and ICESat-2 communities at an in-between location. Thankyou to @esa @esa_cryosat and @NASAEarth for a wonderful week!
Really exciting to hear about @esa’s upcoming CRISTAL mission from all the speakers this morning at #cryo2ice. This is a Ku/Ka band satellite radar altimeter in a near-polar orbit (from 88• north and to 88• south).
Beyond Ice: ICESat-2 also maps vegetation, and here is Xiaomei Lu talking about applications for measuring crop height

Still going strong here at #cryo2ice in Iceland with @dr_slfarrell showing the shape, structure & seasonal cycle of Arctic sea ice ridges from @NASAEarth’s ICESat-2. Tracking sea ice properties with satellite altimetry is challenging but this team has it all figured out!
Next up at #cryo2ice our own Ben Smith from @UW showing how @esa_cryosat + @NASAEarth’s ICESat-2 + SAR velocities + @polargeospatial @WorldViewSpace imagery can be used for tracking ice changes at the margins of West Antarctica
Story of a slow demise of an Antarctic ice shelf: @CapComCatWalk at #cryo2ice in Iceland shows what happened to Conger-Glenzer Ice Shelf which used to be the eastern part of Shackleton Ice Shelf, East Antarctica — coming soon in @NatureGeosci
Fabulous talk by @BryonyFreer at #Cryo2ice about the drainage of Engelhardt Subglacial Lake and changes in the nearby grounding zone from @NASAEarth’s ICESat-2 @esa_cryosat and @DLR_SpaceAgency’s TerraSAR-X
