BioVeL supports scientists to carry out research on biodiversity by offering computerized tools ("workflows") to process large amounts of data from your own and cross-disciplinary sources, as well as tools for designing and running workflows. The Biome-BGC is a process-based biogeochemical model family (originally from NTSG, University of Montana, USA) that can be used to simulate carbon, nitrogen and water pools and fluxes of different terrestrial ecosystems. Another branch of the original model was developed and improved (see: Biome-BGC MuSo), and a Web service and workflow based open modelling environment was constructed and deployed for supporting ecosystem modelling research. BioVeL is funded by the EU’s Seventh Framework Program, grant no. 283359.
