PISM, a Parallel Ice Sheet Model
Contributed by Constantine Khrulev, University of Alaska Fairbanks
PISM is an open-source modelling framework for ice sheets and glaciers jointly developed at the University of Alaska Fairbanks (UAF) and the Potsdam Institute for Climate Impact Research (PIK).
In the 25 or so years from the early days of PISM's development, it has evolved from a serial isothermal ice dynamics model to a parallel, modular framework implementing a hierarchy of stress balance approximations, an enthalpy-based energy conservation model, a mass-conserving basal hydrology model, an intermediate complexity glacial isostatic adjustment component, and extensible coupling to ocean and atmosphere models.
PISM users participated in many community projects and model intercomparisons, producing over 200 peer reviewed publications. Its applications range from projections of contributions from Antarctica and Greenland to sea level rise and papers describing advances in modeling of some key physical processes controlling the behavior of ice sheets to modeling the glaciation of Pavonis Mons, Mars and inferring paleoclimate in south-west Turkey.
