PERMOS Reports

We regularly report about our permafrost measurements in the Swiss Alps! Results and figures are available in various reports and publications, online and in print.

The «Swiss Permafrost Bulletin» is our annual online report on the permafrost measurements of one hydrological year, which we compile since 2019. An annual press release on the newest observations is published via the SCNAT. The printed reports on «Permafrost in Switzerland» (Glaciological Reports Permafrost) cover a four year period, which typically corresponds to one contract period of the network. All our reports can be freely downloaded in the list below. Free hardcopies of the Glaciological Reports can be ordered at the PERMOS Office

The Swiss Permafrost Bulletin (SPB) is our annual online report. Here, we describe the most recent measurement results of one hydrological year (1. October to 30. September). The corresponding dataset is published as a DOI release.

Key Graphs

Have a look at our key figures! For each of the observation variables we compile an overview figure. And in the synthesis figure you can find all key findings in one.

 

Browse trough the PERMOS key graphs below to find our key results!

All figures can be downloaded and used freely as long as the PERMOS Network is indicated as the source and the figure caption is used as provided in the slider below. For questions related to the figures, adaptations, or data, contact the PERMOS Office.

Other Reports

PERMOS data are baseline data to describe the long-term permafrost evolution in the Swiss Alps. We contribute to reports for the national cryosphere monitoring and (inter)national climate observation.

News and results from the national cryosphere monitoring – including snow, glacier and permafrost – are jointly published each year in the journal of the Swiss Alpine Club (SAC) «Die Alpen – Les Alpes – Le Alpi» in German, French, and Italian (see list on Cryospheric Reports Switzerland below). 

PERMOS contributes to environmental or assessment reports on climate change and its impacts, both nationally and internationally.

For the interested public we annually report in the journal of the Swiss Alpine Club – «Die Alpen/Les Alpes/Le Alpi», together with the national networks for snow and glacier observation. Since 2022, the reports in the printed issue are replaced by focus articles on a recent related topic. The joint annual report is available online.
