Mission

We produce and analyse global observation-based products of carbon and water fluxes using machine learning methods that integrate in situ measurements and satellite information to extrapolate local measurements to continental and global scales. The FLUXCOM initiative has recently been generating a large ensemble of such products for the scientific community. With these products we have been contributing to European projects aiming at synthesizing biogenic and anthropogenic carbon fluxes by integrating top-down atmospheric inversions and bottom-up land flux estimates. The GDM group focusses increasingly on global ecohydrological analysis to better understand carbon-water cycle interactions. We aim at synergistically combining global carbon and water cycle data streams. We develop novel ecohydrological data products based on dense time series of geostationary satellites and by partitioning measured evapotranspiration at FLUXNET sites into transpiration and evaporation.
