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

8/ This is my first published paper out of my Masters at @ceos_um! Thanks to my mentors and colleagues there for all their support!

7/ Big thanks to my co-authors, field team, and mentors for the support! @JulienneStroeve @melting_sea_ice @jclandy @Vishnu_seaice @dustinisleifson @hoiminglam

6/ 🤔 Why does this matter? Snow depth on sea ice is correlated with sea ice thickness. Accurate monitoring helps Arctic communities and climate science.

5/ 🌍 Our method demonstrates that it’s possible to retrieve snow depth in leadless regions, providing critical insights for Arctic monitoring.

4/ 🌊 We validated our results using in situ measurements near Cambridge Bay, Nunavut. On average, Cryo2Ice snow depths underestimated in situ values by 2 to 4 cm, but the snow depth distributions match well between Cryo2ice and in-situ.

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.

2/ ❄️ Snow depth on Arctic sea ice is crucial for understanding ice thickness, ecosystem processes, and supporting human activities. But in leadless regions like the Canadian Arctic, measuring snow depth is particularly challenging.
