Methane Emission from Siberian Wet Polygonal Tundra on Multiple Spatial Scales: Process-based Modelling of Methane Fluxes on the Regional Scale, Lena Delta.
Uncertainties in the carbon budget of high latitude ecosystems are partly due to difficulties in assessing the spatially and temporally highly variable methane emissions of permafrost soils. CH4 contributes significantly to global warming. Arctic regions are most critically influenced by a changing...
