TwoWay: Coupled ModelE – Ice Sheets

This document describes how to set up and run GISS ModelE with coupled dynamic ice sheets via PISM). It ties together work from a number of related modeling projects / repositories:

• twoway (this document; repo): Top-level scripts / makefiles tying together other projects. Used to generate input files for coupled runs. Also serves as top-level HOWTO documentation. Start reading here!
• icebin (repos icebin and ibmisc): Ice Sheet – Atmosphere coupler. Also includes regridding for elevation classes and Python interface for use in plotting results.
• PISM (repo): Parallel Ice Sheet Model
• discover-docs (repo): System-specific documentation for those using the NCCS discover <https://nccs.nasa.gov>_ supercomputer.
