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.🌍❄️

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 ⬇️

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 🙃
