Documentation for PISM, a parallel Ice Sheet Model

NEWS: Version 0.6.2 is out.

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

A system of conservative regridding for ice–atmosphere coupling in a GCM
investigators: R. Fischer, S. Nowicki, M. Kelley, and G. A. Schmidt
journal: Geosci. Model Dev.

This paper describes a conservative method using elevation classes to regrid surface mass balance fields between low-resolution GCMs and high-resolution ice sheet models. The proposed transformations are both mass and energy conserving, making them suitable for two-way coupling between climate and ice sheet models. These transformations are implemented in Glint2, a library used to couple atmosphere models with ice models.

Mass-conserving subglacial hydrology in PISM

In a Geoscientific Model Development Discussion paper, UAF author Ed Bueler and IMAU author Ward Van Pelt describe PISM's new mass conserving subglacial hydrology models.

For the PISM user with an interest in subglacial hydrology this paper provides a detailed description of all the subglacial hydrology models available in PISM versions v0.6 and above, along with a stability analysis, verification, and an application to the Greenland ice sheet.

PISM 0.6.1 has bug fixes

Only fixes and improvements that should not break existing functionality are included in this release. We recommend updating from v0.6 unless you have a good reason against it. Upgrade by doing “git pull” in the PISM source tree. (Or get a new tagged “.tar.gz” or “.zip” at github.com/pism/pism/releases.) Then do “make install” in the build directory.

For a full list of changes since v0.6, please see https://github.com/pism/pism/blob/stable0.6/CHANGES.md

Send email to help@pism-docs.org for help with any version of PISM.

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.
