The SOERE CRYOBS-Clim aims at gathering monitoring strategies and observations performed on mountain glaciers, polar ice-sheets, seasonal snow cover and mountain permafrost in different regions (European Alps, tropical Andes, Himalayas, Antarctica,Svalbard). It addresses major societal issues such as water resources, ice-related hazards, atmospheric processes, avalanches, sea level rise, global climate change, … The observation strategy is based on in-situ (automated and manual) and remote (photogrammetry, LiDAR, satellite) monitoring of snow and ice related variables, which are conducted at different spatial scales (from tens of square meters to tens of square kilometers) and different time scales (from hourly to decadal) depending on the observation purpose. Many variables of interest are challenging to measure, requiring the developments of innovative technology. An overview of data, new technologies and examples of significant results obtained in he framework of CRYOBS-CLIM will be given in the presentation.
