ESA DUE Permafrost
The PERMAFROST project was funded by the European Space Agency (ESA) Data User Element (DUE) program from 2009 to 2012. The objective of this project was to establish a permafrost monitoring system based on satellite data. The project defined, demonstrated and validated Earth Observation products essential for permafrost monitoring in the pan-boreal and pan-arctic zone. Products include pan-arctic and regional time series of land surface temperature time, regional time series of surface soil moisture and timing of freeze-thaw, regional waterbody inventories, and regional digital elevation models.
