Research

The Greenhouse Gas Modelling Group studies interactions between the atmosphere, biosphere, and hydrosphere through biogeochemical modelling supported by data‑assimilation and numerical methods.

We have strong expertise in studying is on greenhouse gas dynamics in peatlands and other wetlands, where CO₂ and CH₄ fluxes strongly influence climate impacts. We assess how land management — such as drainage, rewetting, and restoration — shapes these fluxes and long‑term GHG balances. We also examine carbon dynamics in forests, forest management and the role of forest fires and how a warming climate is likely to change forests and their GHG exchange with the atmosphere.

Our work extends from plot‑level to global scales, with emphasis on northern high‑latitude regions. We use land‑surface and process‑based models, including JSBACH-HIMMELI and LandscapeDNDC. We also apply inverse modelling to estimate both natural and anthropogenic GHG fluxes from atmospheric observations, enabling a comprehensive understanding of regional and global GHG budgets and supporting the verification of climate impacts from management and restoration.
