Climate-related Biogeochemical Modelling (CBM) research group

Aims
The CBM research group aims at understanding key carbon cycle processes and their interactions to water and energy balances, and nutrient dynamics from laboratory to global scale. The geographical focus is on northern hemisphere ecosystems. We are advancing dynamic models, such as the land surface scheme JSBACH, a Lichens and Bryophyte model (LiBry), or a hydrological model (VIC-BGC, VICaSU) based on observations at laboratory to ecosystem level. Being part of the Bolin Centre for Climate Research (RA4), the group addresses four main biogeochemical research themes in relation to climate: Soil process dynamics and related GHG balances in particular in permafrost soils; soil-vegetation interactions in northern high latitudes; spatial pattern of vegetation turnover processes; and aquatic carbon and nutrient dynamics.
