Parallel Ice Sheet Model (PISM)

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).
