The Parallel Ice Sheet Model PISM v1.2 is open source and capable of high resolution. It has been widely adopted as a tool for doing science.

Features include:

Postdoctoral Scientist: ice-sheet/climate modeller at MPI-M (Hamburg)

The MPI-Earth group at MPI-M (Hamburg) is looking for a postdoc. PISM experience “would be of advantage”. For more information see the CRYOLIST post.

the 100th PISM-using paper!

At the end of May we found the 100th PISM-using paper:

L. B. Stap, J. Sutter, G. Knorr, M. Stärz, G. Lohmann (2019) Transient Variability of the Miocene Antarctic Ice Sheet Smaller Than Equilibrium Differences. Geophysical Research Letters 46 (8) pp. 4288–4298

See the publications page for a complete-as-far-as-we-know list of the first 100 published PISM applications, back to the first one in 2007.

We find PISM-using papers by following citations, so there may be others out there we do not know about. Authors who want to help us keep track should follow the advice at the acknowledgments documentation.

Here is one view of the PISM papers, sorted by the not-to-be-trusted “journal impact factor” of the journals in which they appear:

The most popular five journals for PISM papers are The Cryosphere, Journal of Glaciology, Journal of Geophysical Research: Earth Surface, Nature, and Geophysical Research Letters; excellent journals all. (Figuring-out the rest of journal abbreviations is an exercise for the reader.)

It is interesting to note that only 22% of PISM-using publications have a UAF-based co-author:

PISM is a tool used throughout the world by scientists needing an ice sheet model, whether or not they have a connection to the UAF developers. So we appreciate NASA and NSF support here at UAF, which has always made our open-source release model possible. We continue to push PISM development in a variety of directions, and we look forward to seeing the next 100 PISM papers!

The UAF PISM developers are currently busy getting PISM ready for ISMIP6. We are implementing all the required parameterizations for Greenland and we are making it easy to output fields in the requested MKS system, use the ISMIP6 variable names and output the requested fields with a shorthand.

Stay tuned.

Version 1.1

PISM v1.1 was tagged on 7 December 2018. It includes a large number of model improvements and issue resolutions (see the change log), but it is an incremental release. Please use this version, or the (master branch), unless you have a good reason to use an older one!

PISM is jointly developed at the University of Alaska, Fairbanks (UAF) and the Potsdam Institute for Climate Impact Research (PIK). For more about the team see the UAF Developers and PIK Developers pages.

UAF developers, who are in the Glaciers Group at the GI, are supported by NASA's Modeling, Analysis, and Prediction and Cryospheric Sciences Programs (grants NAG5-11371, NNX09AJ38C, NNX13AM16G, NNX16AQ40G, NNX17AG65G) and by NSF grants PLR-1603799 and PLR-1644277.
