The aim of the Swiss Permafrost Monitoring Network (PERMOS) is the systematic long-term documentation of state and changes of mountain permafrost in the Swiss Alps. PERMOS was initiated in the 1990ies and is operational since the year 2000. The network receives substantial financial support from the GCOS Switzerland, the Federal Office for the Environment and the Swiss Academy of Sciences and is carried by six partner institutions (ETH Zurich, SLF Davos, Universities of Fribourg (UniFR), Lausanne (UniL), Southern Switzerland (SUPSI) and Zurich (UZH)).

This web site provides information on the monitoring strategy, observation sites, PERMOS partners, and PERMOS Supporter (funding institutions). All PERMOS publications as well as general information on mountain permafrost are also available.

PERMOS includes three types of observations which are taken at sites on different landforms in varying topographic settings: (1) ground temperatures measured in boreholes and at the surface near to the drill site, (2) changes in subsurface ice and unfrozen water content at the drill sites by geo-electrical surveys, and (3) velocities of permafrost creep determined by geodetic surveys and photogrammetry. In addition, fast mass movements from permafrost areas (e.g., rock fall) are documented in an invent ory.

Did you observe rock fall in the Alps...?
