User's documentation

• The Installation Manual (updated on November 09, 2009) describes how to download PISM source code and install it and the libraries it needs. Installation of PISM for Debian-based Linux (like Ubuntu) is smoothest, but many other Unix flavors including SUSE, Cray, and Mac OS X have been used with success.
• The User's Manual (updated on November 09, 2009) describes how to run PISM for certain simplified geometry situations and illustrates how PISM's numerical approximations are verified. It also describes how to use PISM as a Greenland ice sheet model or a Ross ice shelf model, with basic publicly-available data.

Technical documentation

• PISM class, namespace, and source file browser (automatically generated by doxygen on February 13, 2010)
• Get manuals for your version by

  cd pism-dev/doc/
  make

  Then view installation.pdf (Installation Manual), manual.pdf (User's Manual), and doxy/html/index.html (PISM class browser). This requires LaTeX and doxygen.
• PISM is a C++ program which uses the
  • uses the PETSc library for parallel numerics
  • uses the MPI standard for interprocess communication
  • reads and writes NetCDF files
  • automatically converts units by using UDUNITS
  • and generates CF 1.4-compliant NetCDF files
• Some key journal articles on PISM design and applications.

Development of PISM is supported by NASA's Modeling, Analysis, and Prediction (MAP) program (grant #NNX09AJ38G, 2009--2013), and formerly by NASA's Cryospheric Sciences program (grant #NAG5-11371, 2002--2008).
