Within the project, we intend to create an observation-simulation system that quantifies all necessary interactions between soil, vegetation and atmosphere across a wide range of spatial and temporal scales. The spatial scales range from the size of the stomata (10 – 100μm) to the size of the atmospheric boundary layer (~1 km), whereas the temporal scales range from second and minute scale dynamics to diurnal and seasonal cycles.

During my PhD, I will include the modelling of CO2 and H2O stable isotopologues in Large Eddy Simulations. Thanks to new measurements techniques to calculate isotopolgues fluxes (that are being developed within the project and which involve the participation of another PhD student), the simulations can provide insights to the mechanisms that lie behind and at the same time being validated against observations. A second part of the project is to derive relationships of the land processes to larger spatiotemporal scales using a hierarchy of models. The scaling laws provide a basis for parameterizations that will be systematically evaluated in grassland and forest ecosystems.
