One of the major challenges in the 21st century is to understand better the impact of Global Change from regional to global scales, to develop scientificly sound mitigation and adaptation strategies in view of the growing human population and the increasing demand for natural resources.

Earth System Modelling at KIT-Campus Alpin therefore aims - in close cooperation with field and laboratory measurements - to develop improved methods to be applied in the field of analytical earth system research. Modelling activities at KIT-Campus Alpin improve our understanding of physical, chemical and biological processes as well as human impacts influence the dynamics of the biosphere-hydrosphere-atmosphere system, especially with regard to feedback mechanisms of Global Change. and model development and application at KIT-Campus Alpin concentrate on the different compartments of the Earth System and various spatial and temporal scales, but also aim to link integratively single models to .   

 

As Earth-system modelling is generally not restricted to one compartment, the development of coupled models is a core activity at IMK-IFU.

Biosphere-atmosphere coupling

  • LandscapeDNDC: The LandscapeDNDC-Framework has been extended to a fully distributed hydrology model solving the 3-d Richardson Equation synchronously with the soil biogeochemistry. 

 

Meteorology-chemistry coupling

  • The  large-eddy simulation (LES) model for atmospheric and oceanic flows PALM-4U (Parallelized Large-Eddy Simulation Model for Urban applications) was extended by atmospheric chemistry at IMK-IFU.
  • The online coupled meteorology-atmospheric chemistry model WRF/Chem is applied for investigations of feedback processes between air quality and meteorology

 

Coupling of hydrological models

  • WRF-hydro
  • LSM-HS
