Predicting Ice Sheet and Climate Evolution at Extreme Scales (PISCEES)

PISCEES is a SciDAC Earth System Modeling project with the following goals:

  • To develop and apply robust, accurate, and scalable dynamical cores for ice sheet modeling on structured and unstructured meshes with adaptive refinements
  • To evaluate ice sheet models using new tools and data sets for verification and validation (V&V) and uncertainty quantification (UQ)
  • To integrate these models and tools in the Community Ice Sheet Model (CISM) and Community Earth System Model (CESM).

Using improved estimates of ice sheet initial conditions, we will simulate decade-to-century-scale evolution of the Greenland and Antarctic ice sheets, running CISM both in standalone mode and coupled to CESM. We aim to provide useful, credible predictions, including uncertainty ranges, of future ice-sheet mass loss and resulting changes in climate and sea level.

 

PISCEES is jointly funded by the Office of Biological and Environmental Research (BER) and the Office of Advanced Scientific Computing Research (ASCR) of the DOE Office of Science.
