I haven't read through the paper in enough detail to see if the actual model used is mentioned, but I did see that they use CCSM forcings. You can see the relevant CESM models here: http://www2.cesm.ucar.edu/models http://www2.cesm.ucar.edu/models. They provide links to the various components as well as validated configurations for you to play with. If you are specifically interested in ice sheet models you could look at these: PISM - http://pism-docs.org/wiki/doku.php http://pism-docs.org/wiki/doku.php CISM - http://oceans11.lanl.gov/cism/ http://oceans11.lanl.gov/cism/ ISSM - https://issm.jpl.nasa.gov/ https://issm.jpl.nasa.gov/
