Process-based modeling of greenhouse gases and peat accumulation in rewetted fens (A07)

• Subject Area: Physical Geography
• Term: since 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 531801029

We will develop a process-based modeling and data assimilation framework based on the soil profile model COMISSION to identify the relative importance of different mechanisms for peat decomposition and formation. Besides CO2 production, we will also model the production and consumption of the GHG CH4 and N2O, taking into account the availability of oxygen and other terminal electron acceptors at different peat depths. This will be achieved by model-data comparison and integration with data from the mesocosm experiment MCExp rewetted peat, Screening Sites, and Core Sites.
