Current Research: Methane processes and controls

After CO
2, 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 CH
4 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).
