Abstract
A detailed process-based methane module for a global land surface scheme has
been developed which is general enough to be applied in permafrost regions as
well as wetlands outside permafrost areas. Methane production, oxidation and
transport by ebullition, diffusion and plants are represented. In this model,
oxygen has been explicitly incorporated into diffusion, transport by plants
and two oxidation processes, of which one uses soil oxygen, while the other
uses oxygen that is available via roots. Permafrost and wetland soils show
special behaviour, such as variable soil pore space due to freezing and
thawing or water table depths due to changing soil water content. This has
been integrated directly into the methane-related processes. A detailed
application at the Samoylov polygonal tundra site, Lena River Delta, Russia,
is used for evaluation purposes. The application at Samoylov also shows
differences in the importance of the several transport processes and in the
methane dynamics under varying soil moisture, ice and temperature conditions
during different seasons and on different microsites. These microsites are
the elevated moist polygonal rim and the depressed wet polygonal centre. The
evaluation shows sufficiently good agreement with field observations despite
the fact that the module has not been specifically calibrated to these data.
This methane module is designed such that the advanced land surface scheme is
able to model recent and future methane fluxes from periglacial landscapes
across scales. In addition, the methane contribution to carbon cycle–climate
feedback mechanisms can be quantified when running coupled to an atmospheric
model.
