Permafrost status is monitored as part of GTN-P (Global Terrestrial Network on Permafrost). Remotely sensed information complements these sub-ground datasets with surface and near-surface measurements. Surface characteristics such as temperature, moisture, snow, surface waters dynamics, and land cover can be used to support modelling of sub-ground thermal properties over larger regions. In addition, remotely sensed data offer the possibility to capture landscape heterogeneity and thus representativity of in-situ point measurements.
Datasets available within the framework of the DUE Permafrost and STSE ALANIS-Methane projects are utilized for circumpolar characterization of GTN-P sites with respect to potential multi-scale applications in this study. This investigation supports the FP7 funded project PAGE21 - Changing Permafrost in the Arctic and its Global Effects in the 21st Century.
