I am curious to know if the surface energy balance parameterization in CLM4.5 for a bare glaciated land surface (with no snow on it) constrains the top glacier layer to be at or below the melting point. The CLM4.5 documentation states that glaciers are initialized below freezing in the model (250 K) but does not indicate that ice is present in the latent heat flux calculation. Is this so? From what I can tell, glaciers are treated as “soil” with ice like albedo and conductivity, but can theoretically have a ground temperature that exceeds the melting point. Is this so?
Also, I am specifically asking about glacier units that are fed in from a surface file and fixed on the land grid (do not evolve dynamically, e.g. beta version of CESM with 2-way coupling to CISM).
