Parallel netCDF4 allows first Greenland simulation on a 1km grid

Published: Apr 12, 2012 by The PISM Authors

The upcoming stable 0.5 release supports parallel NetCDF4, thus avoiding the file size limitations of netCDF3. This allows for unprecedented grid resolutions.

Here at UAF we have performed the first Greenland 1km 100-year simulations, run in parallel on 512 cores.

Observed and modeled surface speeds in meters per year.

  • (a) observed (Joughin et al., 2010)
  • (b) PISM constant-climate initialization
  • (c) PISM paleo-climate initialization

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,, 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.
