Peatlands emit significant amount of methane, which has strong climate warming effect. In MeWen project we aim to improve the understanding of methane emission with novel isotope approach. We will install below and aboveground real-time monitoring system in Siikaneva fen and bog to continuously follow CH4 dynamics in the peat and 13C isotope on the surface. Meanwhile, we will apply isotope tracer in the field to specify wetland methane production and oxidation. We will use the measured data to update CH4 model HIMMELI. Ultimately for the first time, high-frequency annual CH4 isotope measurement from the peatland will be used to improve the process-based CH4 modelling.
