The project goal is to simulate the amount and variations of near-surface moisture amount, and compare them with the satellite-observed estimates.

A global land-atmosphere-ocean climate model with physically based thaw/freeze processes is used to simulate the near-surface wetness, which is compared with the satellite data provided for the Data User Element (DUE) permafrost project by the European Space Agency (ESA).

The anticipated results are quantitative and qualitative assessments of the performance of both sides (the model and the satellite product).

The contribution to synthesis or integration of arctic science will be the mprovement and validation of the thermo-hydrological and freeze/thaw processes in the physical terrestrial schemes.
