Background & Motivation

Background

  • Global (environmental / climate) change is affecting terrestrial systems at all scales
  • These physical system changes will be accompanied by major state changes of land surfaces and ecosystems and of the services provided by them with multiple (socioeconomic) impacts
  • Many processes are still poorly understood or reproduced by models

Motvation

  • Supercomputing offers new perspectives for the simulation, understanding and sustainable management of terrestrial systems
  • Demanding numerical models to investigate terrestrial system processes due to:

    1. Complex, ninlinear transport of energy, mass and momentum
    2. Interactions and feedback mechanisms between different compartments of the coupled geo-ecosystem (subsurface, land-surface, atmosphere, reservoirs)
    3. Multiple spatio-temporal scales, high resolutions, potentially long runtime
    4. The need for ensemble simulations to estimate uncertainties
  • Strong record of Geoverbund ABC/J scientists in computational geosciences and terrestrial system simulations
  • Availability of computational resources
