Global Terrestrial Network - Permafrost (GTN-P)
Data Access

Data availability: Data are available online. Global Terrestrial Network for Permafrost (GTN-P) data for over 550 boreholes from Antarctica, Argentina, China, Canada, Greenland, Italy, Kazakstan, Kyrgyzstan, Mongolia, Norway, Russia, Spain, Sweden, Switzerland, United States can be downloaded as well as borehole metadata.

Data Access and Information on the terrestrial ECVs, including Permafrost, are available in the ECV Data Access Matrix.

Access the Databases

• Frozen Ground Data Center at the National Snow and Icen Data Center. Permafrost and seasonally frozen ground regions occupy approximately 24% and 60%, respectively, of the exposed land surface in the Northern Hemisphere. The actual area underlain by permafrost is approximately 12% to 18% of the exposed land area. Frozen ground data and information collected over past decades, and to be collected in the future, are critical for fundamental process understanding, environmental change detection, impact assessment, model validation, and engineering applications. However, much of this information remains widely dispersed and unavailable to the science and engineering communities, and some data are in danger of being lost permanently.

• TSP NORWAY: Thermal State of Permafrost in Norway and Svalbard - An IPY Permafrost Observatory Project funded by the Research Council of Norway The NORPERM permafrost database provides information on ground temperatures from boreholes and from the near-surface using miniloggers (MTDs). The database was established during the International Polar Year as one of the main goals of the project TSP Norway - "A Contribution to the Thermal State of Permafrost in Norway and Svalbard".

• Canadian Permafrost Monitoring Network. Canada, through the Geological Survey of Canada (GSC) is an active participant on the GTN-P organization and implementation committee and is also responsible for the establishment of the data management centre.
