The land-ice component remains MPAS-Albany-landice and is a static ice sheet. Major changes since version 1 include :…preparation for using an active ice sheet such as:
MALI code was moved from a submodule to instead exist directly within the E3SM repository.
An ice shelf damage evolution scheme was added, but is not yet coupled to calving or advection.
A von Mises tensile stress calving schemes was implemented and the calving algorithm was rewritten to eliminate a number of bugs.
The grounded marine terminus ocean melting scheme from ISMIP6-Greenland was implemented.
The option to use a regularized Coulomb basal friction law and a general power law basal friction law were added.
The sub-ice-shelf melting scheme from ISMIP6-Antarctica was added.
The prescribed mask-calving forcing scheme from ISMIP6-Antarctica was added.
Coupler/Configurations
All components allow regional refinement of their meshes and an example of refinement in and around North America is provided.
