Current
Research: Methane processes and controls
After CO2, methane is the most important greenhouse
gas with, depending on the time horizon, at least 23x stronger radiative
forcing per molecule. The growth rate of atmospheric methane increased
substantially from 1950 to 1990, but has subsequently declined and has
shown some unexplained oscillations in recent years. Wetlands constitute
the major natural emission source of methane to the atmosphere and subarctic
peatlands are one of the most sensitive ecosystems which react in a direct
way to climate warming. Already now we can observe how formations underlain
by permafrost are rapidly disintegrating and changing into a wetter hydrological
state. These changes have triggered visible and substantial changes in
the vegetation distribution and may represent an important feedback mechanism
in changing climate through changes in the land-atmosphere exchanges
of trace gases such as carbon dioxide (CO2) and methane (CH4).
In this study, wetlands will be included in biosphere models and coupled to
parameterizations of CH4 emissions in order to study the effect of wetlands
on the CH4 cycle. A hydrological model will be embedded in a climate
model to determine natural wetland areas. The budget of methane will be
studied by introducing a biospheric model and a chemistry-aerosol component
to the Earth System Models. The main task of this study is to gather and
synthesize existing data as well as produce new data on landscape scale
and inter-annual variation in CH4 fluxes and the
factors controlling them. These data will in turn be used for testing the
associated modelling efforts mentioned above. The techniques to be employed
include both small scale chamber flux measurements as well as micrometeorological
studies of CH4 fluxes in natural wetlands.
This
project contributes to the science objective
3 (Improve understanding of natural sources of CH4 and their responses to human activities) of GREENCYCLES
and has links to the projects of Roxana (ESR IX).
