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

A two-year PostDoc positions in ice sheet and Earth system modelling is available in the Ice Dynamics group, as part of the new Earth Resilience Science Unit (ERSU), at the Potsdam Institute for Climate Impact Research (PIK).

Two PhD fellowship positions in ice sheet modelling are advertised at the Niels Bohr Institute, University of Copenhagen.

The Alfred Wegener Institute, Bremerhaven, is offering a PhD position in the field of coupled ice sheet-ocean modelling. The core of the project is to run simulations with FESOM-PISM (a coupled ocean-ice shelf-ice sheet model with evolving cavity geometries) for different 21st-century climate projections to obtain well-constrained trajectories of future ice mass loss from the vast Antarctic Ice Sheet. Model results will feed into a fingerprinting method that considers the ocean response as well as gravitational effects and contributions from other sources. The final product will be a time series of global maps of regional sea-level variations that consider all of the most relevant processes.
