PISM stable0.3 is released

Published: May 23, 2010 by The PISM Authors

PISM version stable0.3 is available. See the stable version page to check out a copy of the source code. Send email to help@pism-docs.org for help with any version of PISM.

Compared to stable0.2, the new version

  • uses a polythermal, enthalpy-based energy conservation scheme
  • includes improved atmosphere, surface processes and ocean model structure
  • puts all model parameters and physical constants in a configuration file which can be changed without re-compiling PISM
  • has a better User’s Manual
  • comes with a command-line option Cheat-Sheet
  • has a better HTML PISM Source Code Browser
  • supports saving scalar, 2D and 3D diagnostics at given times during the run
  • allows climate forcing using spatially-varying “anomalies” (near-surface air temperature and precipitation)
  • includes better metadata handling
  • can be stopped and restarted without affecting results of a run
  • has more software tests (including regression tests)
  • has an automatic vertical grid extension mechanism
  • performs area and volume calculations using WGS84 datum to correct projection error
  • makes the computation of the age of the ice optional, for efficiency
  • has easier-to-extend source code
  • comes with three worked examples: Antarctica, Greenland, Storglaciaren


Latest news

PISM 2.0 is out

PISM developers have been hard at work to bring you a brand new version of PISM, packed with new features. After years of development, PISM finally includes a Blatter solver, warranting a new major version: PISM 2.0.

Version 1.2

We are pleased to announce the release of the Parallel Ice Sheet Model (PISM) v1.2.

MPI-M Hamburg, Germany: open postdoc for coupled atmosphere-ocean-ice sheet model

The Max Planck Institute for Meteorology (MPI-M) contributes to the BMBF project “From the Last Interglacial to the Anthropocene: Modeling a Complete Glacial Cycle” (PalMod, www.palmod.de), which aims at simulating the climate from the peak of the last interglacial up to the present using comprehensive Earth System Models. Phase II of this project has an open position Postdoctoral Scientist (W073). The successful candidate will be part of a local team performing and analysing long-term transient simulations covering the last glacial and the transition into the Holocene with an interactively coupled atmosphere-ocean-ice sheet model. Additionally, the candidate will contribute to the continued development of this model. The model system consists of the MPI-Earth system model, the ice sheet model PISM, and the solid-earth model VILMA.
