 Abstract: A process-basemd odelh as beend evelopedin
order to calculate methane emissions from natural wetlands
as a function of the hydrologic and thermal conditions in
the soil. The considered processes in the model are methane
production, methane consumption and transport of methane
by diffusion, ebullition and through plants. The model has
been tested against data from a three-year field study from a
Michigan peatland. The interannual and seasonal variations
of the modelled methane emissions and methane concentration
profiles are in good agreement with the observations.
During the growing season the main emission pathway proceeds
through plants. Ebullition occurs whenever the water
table is above the soil surface, while diffusion is only significant
in the first 15 days after a drop of the water table below
the peat surface.
