Improving a plot-scale methane emission model and its performance at a Northeastern Siberian tundra site

Abstract: Abstract. In order to better address the feedbacks between climate and wetland methane (CH4) emissions, we tested several mechanistic improvements to the wetland CH4 emission model Peatland-VU with a longer Arctic dataset than any other model: (1) inclusion of an improved hydrological module; (2) incorporation of a gross primary productivity (GPP) module; (3) a more realistic soil-freezing scheme. A long time series of field measurements (2003–2010) from a tundra site in Northeastern Siberia is used to valida… Show more

“…talyk is in the continuous permafrost zone with an average active-layer thickness (ALT) of 42 cm. Dry areas show a reduced ALT of 12-28 cm, while the ALT in wetter areas ranges from 22-50 cm (Mi et al, 2013). The Circumpolar Arctic Vegetation Map classifies the vegetation at the study site as tussock-sedge, dwarf-shrub, moss tundra .…”
