Simulation and Data Laboratory Terrestrial Systems

The Simulation and Data Lab Terrestrial Systems (SDLTS) focuses on numerical simulation of terrestrial system and hydrological processes across scales, leveraging and the pushing the limits of high-performance computing and scientific software.

Global change is affecting terrestrial systems at all scales. It results in major changes of the land surface and ecosystems and of the services provided by them with several socioeconomic impacts. Many processes are still poorly understood or reproduced by models.

Supercomputing offers new perspectives for the simulation, understanding and sustainable management of terrestrial systems. It enables the application of demanding numerical models to investigate terrestrial system processes:

  • Complex, nonlinear transport of energy, mass and momentum
  • Interactions and feedback mechanisms between different compartments of the coupled geo-eco-hydro system (subsurface, land-surface, atmosphere, reservoirs)
  • Multiple spatio-temporal scales, high resolutions, potentially long runtime
  • Regional Earth system modelling
  • Environmental hydrodynamics and transport
  • Ensemble simulations, uncertainty estimation and data assimilation

SDLTS is part of the Centre for HPSC TerrSys at the Jülich Supercomputing Centre (JSC), an initiative of Geoverbund ABC/J. SDLTS strongly supports the activities of HPSC TerrSys and their work in computational geosciences and terrestrial system simulations. SDLTS more broadly supports the Geoverbund ABC/J with scientific and technical support for their research activities on state-of-the-art supercomputers.

Within the Program-oriented Funding (PoF IV) of Helmholtz Information, this group contributes to Program 1 “Engineering Digital Futures”, Topic 1 “Enabling Computational- & Data-Intensive Science and Engineering”, and it is part of the Joint Lab Exascale Earth System Modelling (ExaESM) and of the Center for Advanced Simulation and Analytics (CASA).
