CRYOBS-CLIM ((The CRYosphère, a CLIMATE Observatory), is labeled in 2015 and is structured around the monitoring of the major components of the cryosphere: mountain glaciers / polar ice caps, snow cover and mountain permafrost. CRYOBS-CLIM is a SOERE grouping together 8 French laboratories and foreign partners, representing 53 actors in total. This new SOERE brings together 3 communities of the cryosphere with common challenges: (1) the study of glaciers and polar ice caps, the elementary brick of the SOERE, benefiting from the double SNO INSU label under the name GLACIOCLIM (the GLACiers, a CLIMAT Observatory) And the SOERE GLACIOCLIM label also over the period 2011-2015. In the SOERE GLACIOCLIM the Svalbard glaciers component was added to CRYOBS-CLIM; (Ii) the study of the snowpack; Iii) the study of mountain permafrost. The emergence of the SOERE CRYOBS-CLIM enabled the structuring of a large part of the community working on the cryosphere in France around the monitoring of key variables of climate change (mass and energy balances, internal variables). The SOERE is a key tool for proposing long-term and high-quality observations of the cryosphere in various climatic zones (tropical, temperate and polar regions) in order to meet major societal challenges (resources, sea levels, hazards, etc…). The strategy implemented, combining multi-level observations (in-situ and remote sensing) and models, responds to “regional” follow-ups, but for motivations of international dimensions in the context of climate change.
