Research direction
No files, tests, or entry points are identified. Start by tracing how snow accumulates on non-glaciated and glaciated cells, then determine a capping and runoff behavior that prevents persistent excessive snow from distorting the surface energy budget; ice-sheet handling is explicitly deferred.

Description
Snowfall in the high latitudes can accumulate in unlimited quantities, both over non-glaciated and glaciated land. This is a problem for glaciers if I ever coupled to an interactive ocean, but it turns out it may ALSO be a problem for non-glaciated land, as having 100s of kg/m2 of snow on even a few gridcells all year round is messing with the local surface energy budget and making it artificially cold. I didn't expect that to be an issue, but it appears that it is. Consider capping total snow on non-glaciated cells to some fixed amount (and chucking the rest into run off? Not perfect, but might solve the temperature issue). Have to do something for ice sheets, too, but worry about htat later.
