Land surface–atmosphere interactions play an important role in fueling the energy and water cycle of the atmospheric boundary layer. In-situ and ground based remote sensing observations as well as large-eddy simulations provide detailed insight in these exchange processes. This information needs to be aggregated to larger scales of climate models and satellite observations.
Research activities of the working group are focused on experimental and numerical investigations to better understand the interactions between the atmospheric boundary layer and the land surface. The maintains the land component of M4T (Max-Planck Institute for Meteorology Mobile Toolkit) comprising sensors to observe locally fluxes between these two compartment as well as the state of the boundary layer and the land surface. The group is a joint working group of the Meteorological Institute of the University of Hamburg and the Max Planck Institute for Meteorology. At the University the group is entitled "Atmosphere measurements and process modelling".
