apcraig and others added 3 commits August 22, 2023 10:11

…Consortium#454)

* Corrects thin ice/snow treatment of enthalpy and other tracers

Adopted from E3SM-Project/E3SM#5630

"This fix redistributes enthalpy and other tracers evenly in snow and ice when their
respective thicknesses are < 1e-15 . Previously, these tracers were zero'd non-conservatively.
Also corrects a bug in the zeroing of snow thicknesses, and removes snow in thickness_changes
if the ice vanishes."

* Clean up modifications

Tested in E3SM with results as expected. Will combine with the next PR from the Consortium for more complete testing and linking as the E3SM submodule in the icepack-integration branch.
