Here are three topical pages at the webpage of Prof. Anders Levermann describing work using and developing PISM at PIK:
Developers at the Potsdam Institute for Climate Impact Research (PIK), Germany, created the Potsdam Parallel Ice Sheet Model, PISM-PIK, in 2008–2009 as a derived class of PISM stable0.2. Changes were made to the PISM base model in spring 2011 so that PISM-PIK capabilities are now part of the stable0.4 release of PISM itself, and of future releases.
Processes like ice shelf calving and stress boundary conditions become increasingly important particularly for future sea level projections due to their effect on the dynamics upstream of the grounding line. PIK has introduced modifications of PISM ice shelf dynamics with a special focus on modeling the Antarctic ice sheet-shelf system. New features and applications include:
