❓Why is this important? Mountain permafrost matters for #slopestability & #waterresources. #geographymatters
✨I had developed the method for the Alps with colleagues at University of Zurich.
👨🎓Project led by Guillermo Azócar, for Dirección General de Aguas. Thanks to contributors!

First Chilean mountain #permafrost model & map is out!
Preprint: egusphere.copernicus.org/preprints/20...
🌎We used the most complete compilation of permafrost evidences - mainly rock glaciers & boreholes - along with climatic+topographic data to inform a nonlinear statistical model. 📈
