Mpas-Albany Land Ice Model User'S Guide V6.0
The MPAS-Albany Land Ice (MALI) is an unstructured-mesh land ice model (ice sheets or glaciers) capable of using enhanced horizontal resolution in selected regions of the land ice domain. MALI is built using the Model for Prediction Across Scales (MPAS) framework for developing variable resolution E...
