<desc>mpas.ais20km is a uniform-resolution 20km MALI grid of the Antarctic Ice Sheet. It is primarily intended for testing.</desc>

<desc>mpas.ais8to30km is a variable resolution MALI mesh of the Antarctic Ice Sheet with resolution varying from 8 km in fast flowing regions and near the ice-sheet margins to 30 km in the ice-sheet interior. It behaves reasonably well for most of the ice sheet but results in Thwaites Glacier retreating too rapidly due to insufficient resolution there. It is meant as a cheaper alternative to mpas.ais4to20km for testing realistic conditions.</desc>

<desc>mpas.ais4to20km is a variable resolution MALI mesh of the Antarctic Ice Sheet with resolution varying from 4 km in fast flowing regions and near the ice-sheet margins to 20 km in the ice-sheet interior. It was the primary mesh and initial condition used for ISMIP6-Antarctica-2300 and is the primary Antarctic mesh to use for E3SM v3 simulation and development with an active Antarctic Ice Sheet component.</desc>
