Great to be in Greenland and teach with real snow, despite an abnormal warm week.
Teaching in Sisimiut! ❄️ Today, we were out in the snow measuring snow depths after heavy melting over the past few days. Great hands-on experience for the students! #ArcticScience #Fieldwork

📢 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?

Bias in modeled Greenland Ice Sheet melt revealed by ASCAT
Abstract. The runoff of surface melt is the primary driver of mass loss over the Greenland Ice Sheet. An accurate representation of surface melt is crucial for understanding the surface mass balance a...

So true…
Congratulations world! We did it! 1.6C above pre-industrial, really solid effort to get over the line there...

I knew this from @copernicusecmwf.bsky.social was coming out, but I'm not despairing, it's time to double down on the work.

Thrilled to see our former PhD candidate back at the institute, sharing his expertise with the next generation! I’m sure the insights and dedication are truly inspiring;-)
I am teaching a course called “cryosphere physics and observations”. This semester we have invited some former students from the course to come and talk about what they do now. Today, Nicolaj Hansen talked about his work on Antarctica SMB at DMI. Very interesting!
