Permafrost observations are essential to document local and regional effects of climate changes, improve model predictions and contribute to validation of climate models and feedback mechanisms not the least in terms of potential greenhouse gas production. Permafrost monitoring is included in GIOS through the GEM program with data delivery from Zackenberg, the international Arctic Station to the Circumpolar Active Layer Monitoring (CALM) program and data from deep permafrost cores and experimental sites. Within the GIOS collaboration framework, we will establish and further develop a network of comparable permafrost monitoring stations partly established at the Center for permafrost (CENPERM) spanning all climate zones and permafrost conditions (sporadic to continuous permafrost) which makes it optimal for studying the changes anticipated in the coming decades.

Permafrost stations (5-7) along a transect from Kangerlussuaq to Sisimiut consisting of 20 m boreholes and thermistor strings, combined with a weather station to study local scale environmental change will be installed. The existing DTU station in Sisimiut will be upgraded to provide real time data transmission. This expansion of current research to long-term monitoring will fill a current gap in regional and global permafrost observations, allowing for better representation in global climate and earth system models, and will improve our capability to validate regional to local scale engineering challenges.
