The Parallel Ice Sheet Model pism0.7 is an open source, parallel, high-resolution ice sheet model. Features:
|Consistent evidence of increasing Antarctic accumulation with warming|

The Antarctic ice sheet (AIS) will likely experience higher snow accumulation rates in a warmer climate because warmer air has a higher moisture-holding capacity. This paper quantifies the effect based on ice-core data and paleo-climate simulations, which together show a consistent continental-scale accumulation increase of 5 percent per degree Kelvin. (Note ice-core data and GCM-type modelling results agree for the last deglaciation.) However, some of the mass gain of the AIS is offset by dynamical losses induced by accumulation. This is where PISM plays a supporting role in the paper. PISM results were used to generate a response function allowing projections of sea-level fall in terms of continental-scale accumulation changes. In PISM the accumulation changes can and do compete with changes in surface melting and with dynamical losses induced by mechanisms like ocean interaction and sliding.

The Max Planck Institute for Meteorology (MPI-M) is a multidisciplinary center for climate and Earth system research located in Hamburg, Germany. 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.
With respect to this research project, we have an open position for a
The successful candidate will be part of a local team performing and analyzing transient simulations from the last Glacial to the Holocene with an interactively coupled atmosphere-ocean-ice sheet model. Additionally the candidate will contribute to the development of this model. The model system will consist of the MPI-Earth system model and the ice sheet model PISM.

PISM v0.7.1 was released 30 June 2015. In addition to bug fixes this version adds support for PETSc 3.6.1, which was released 22 July 2015.
PETSc 3.6.0 is not supported due to a bug in PETSc. Please use PETSc 3.5.4 or >= 3.6.1 with PISM.
It's summer time! UAF PISM developers are currently writing proposals, working on their own projects, and enjoying the summer. Please give us some slack responding to questions, bug reports, etc. We will try to fix serious bugs as quickly as possible . We'll be back at full strength in the Fall.
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, NNX13AK27G) and by the Arctic Region Supercomputing Center.
