Documentation for PISM, a parallel Ice Sheet Model

NEWS: Nature paper: ice plug in East Antarctica prevents collapse

The Parallel Ice Sheet Model pism0.6 is an open source, parallel, high-resolution ice sheet model. Features:

  • hierarchy of available stress balances
  • marine ice sheet physics, dynamic calving fronts
  • polythermal, enthalpy-based conservation of energy scheme
  • subglacial hydrology and till model
  • extensible coupling to atmospheric and ocean models
  • inversion toolbox in Python
  • verification and validation tools
  • complete documentation for users and developers
  • uses MPI and PETSc for parallel simulations
  • reads and writes CF-compliant NetCDF

Paleo-glaciations of the Shaluli Shan, southeastern Tibetan Plateau
investigators: Fu, P. and 7 others
conference: EGU Annual Meeting, Vienna, Austria, April 07-12, 2013

Geomorphological mapping, 10Be and 26Al exposure dating and glacial modeling are used to reconstruct the glacial history of the Shaluli Shan, southeastern Tibetan Plateau, and to understand the evolution of the glacial landscape. The Haizishan Plateau experienced multiple ice cap glaciations, and 10Be and 26Al exposure ages from bedrock, boulder and saprolite profile samples show limited glacial erosion on some parts of the plateau surface and more than 2 meters of bedrock erosion in other areas. This juxtaposition of high erosion and relict topography suggests that the paleo Haizishan ice cap had a complex basal thermal regime. A numerical glacier model (PISM) is now being used to investigate the thermal regime of the paleo ice cap and patterns of erosion potential. This work provides new insights into the paleoclimatic setting and glacial landscape evolution of the southeast Tibetan Plateau.

Continued NASA funding supports PISM development through 2017

 www.nasa.gov

We have been notified that two PISM-supporting NASA research proposals have been selected for funding, one in the Cryospheric Sciences program and one in the Modeling, Analysis, and Prediction (MAP) program. Our proposed research threads focus on the dynamics of the Greenland ice sheet and on the exploitation of NASA remote observations as constraints. The current MAP grant expires in the next few months, so this news is timely. The new grants support PISM development and application for four years, through mid-2017. They include support for UAF researchers Ed Bueler, Andy Aschwanden, and Mark Fahnestock, and full-time support for scientific programmer Constantine Khroulev.

PISM team

PISM is jointly developed at the University of Alaska, Fairbanks (UAF) and the Potsdam Institute for Climate Impact Research (PIK). UAF developers, who are in the Glaciers Group at the GI, are supported by NASA's Modeling, Analysis, and Prediction and Cryospheric Sciences Programs (grants NAG5-11371, NNX09AJ38C, NNX13AM16G, NNX13AK27G) and by the Arctic Region Supercomputing Center.
