CRYOBS-CLIM (the cryosphere, an observatory of the climate), accredited in 2004, is structured around the monitoring of the major components of the cryosphere: mountain glaciers and polar caps and snow. The aim is to maintain and homogenize a network of reference measurements of these key components of the water cycle in mountain or high latitude regions.
Several glaciers are monitored in the Alps, the Pyrénées, the Andes, the Himalayas and in Antarctica.
Three sites are more specifically dedicated to the study of snow and its transport in the Alps and in Antarctica.

The monitoring of glacier allows to study the relationship between climate variations and glacier mass balances at different spatial scales (from local to regional) by combining field measurements and remote sensing. The aim is to predict the future evolution of glaciers in terms of water resources and their contribution to future sea level rise and to understand their response dynalics to fluctuations in mass balance and thus assess the natural risks of glacial origin.
The monitoring of snow sites allow to document the processes of snow accumulation, melting and wind transport. These sites also allow to characterize the impact of climate change on the water cycle.
Sites and measured variables
On glaciers and polar caps, the aim is to monitor annual, winter and summer ice mass balances, meteorology, and energy balances. At the upstream of some glaciers, hydrological monitoring of flows is also carried out. On sites dedicated to snow study, meteorological variables, height and snow characteristics are monitored.
Partners and further information
The monitoring of the sites of the CRYOBS-CLIM network are financed by CNRS/INSU, IPEV, IRD, INRAE, Météo-France and Grenoble-Alpes University. The monitoring of Andean glaciers benefits from partnerships in Peru and Bolivia and the glaciers in the Himalayas from collaborations with Nepal.
