Current land surface models used to simulate permafrost dynamics are not capable to represent soil erosion [...] between erosion-induced landscape changes and permafrost degradation? In order to answer these crucial questions we will extend and improve the permafrost model CryoGrid3 developed by the Alfred Wegener [...] Background Impacts of permafrost degradation (Graphic: Alfred-Wegener-Institut) Almost a quarter of the land surface of the northern hemisphere of the earth is characterized by permanently frozen soils

Starting from Barrow, long low level flight legs are flown over the permafrost wetland with ascents and descents interspersed for vertical soundings of the boundary layer structure [...] east to west during which the methane concentration accummulates in the boundary layer.
