Abstract. We describe and evaluate version 2.1 of the Community Ice Sheet Model (CISM). CISM is a parallel, 3D thermomechanical model, written mainly in Fortran 90/95, that solves equations for the momentum balance and thickness and temperature evolution of ice sheets. CISM's velocity solver incorporates a hierarchy of Stokes-flow approximations, including shallow-shelf, depth-integrated higher-order, and 3D higher-order. CISM also includes a suite of test cases, links to third-party solver libraries, and parameterizations of physical processes such as basal sliding and iceberg calving. The model has been verified for standard test problems, including the ISMIP-HOM experiments for higher-order models, and has participated in the initMIP–Greenland initialization experiment. In multi-millennial simulations with modern climate forcing on a 4-km grid, CISM reaches a steady state that is broadly consistent with observed flow patterns of the Greenland ice sheet. CISM has been integrated into version 2.0 of the Community Earth System Model, where it is being used for Greenland simulations under past, present and future climates. The code is open-source with extensive documentation, and remains under active development.

Short summary
This paper describes the Community Ice Sheet Model (CISM) version 2.1. CISM solves equations for ice flow, heat conduction, surface melting, and other processes such as basal sliding and iceberg calving. It can be used for ice-sheet-only simulations or as the ice sheet component of the Community Earth System Model. Model solutions have been verified for standard test problems. CISM can efficiently simulate the whole Greenland ice sheet, with results that are broadly consistent with observations.
