We are pleased to announce the release of the Parallel Ice Sheet Model
This release has substantial changes to the code base, but users will
not see many large
differences. The goal of most code changes was to improve modularity
and usability, making PISM easier
to use, maintain and extend.
User-visible changes include the following.
- New mass transport code makes it easier to "balance the books".
- PISM's grids are no longer transposed ((y,x) versus (x,y)).
- Adds an optimized implementation of the GPBLD flow law for the Glen n=3 case.
- Adds von Mises calving.
- Adds more diagnostic quantities (127 spatially-variable fields and
38 scalar variables
- Better code, better documentation, more regression and verification tests.

code is hosted at
PISM is a joint project of developers at the University of Alaska,
Fairbanks and at the
Potsdam Institute for Climate Impact Research (PIK).
Development of PISM is supported by NASA grant NNX17AG65G and NSF
