The Parallel Ice Sheet Model is an open source, parallel, high-resolution ice sheet model that includes:

- A hierarchy of available stress balances
- Marine ice sheet physics, dynamic calving fronts
- A polythermal, enthalpy-based conservation of energy scheme
- Extensible coupling to atmospheric and ocean models
- Verification and validation tools
- `Documentation `_ for users and developers
- Links to MPI_ and PETSc_ for parallel simulations
- Use of `CF-compliant `_  NetCDF_ files for input and output

PISM is jointly developed at the `University of Alaska, Fairbanks (UAF) `_ and the
`Potsdam Institute for Climate Impact Research (PIK) `_. UAF developers are based in
the `Snow, Ice, and Permafrost Group `_ at the `Geophysical Institute `_.

Please see PISM's manual https://www.pism.io/docs/citing for how to acknowledge the use of
PISM and PISM's funding sources. If the manual is not available, please refer to the file
``doc/sphinx/citing/index.rst`` in the PISM repository.

abstract: The Parallel Ice Sheet Model (PISM) is an open-source modelling framework for
  ice sheets and glaciers. Its features include a hierarchy of available stress balances,
  marine ice sheet physics with dynamic calving fronts, an enthalpy-based conservation of
  energy scheme, bed deformation and subglacial hydrology components, extensible coupling
  to atmospheric and ocean models, and comprehensive user documentation. PISM uses
  distributed-memory (PETSc- and MPI-based) parallelism for high-resolution simulations.

  PISM is jointly developed at the University of Alaska, Fairbanks (UAF) and the Potsdam
  Institute for Climate Impact Research (PIK).
