Description:
I noticed in @adrifoster's FATES albedo results that upplim_destruct_metamorph seemed to have a positive effect on FSR in the regions where we're trying to melt snow / grow plants. Looking at other plots in #3 it seems like the low value for this parameter is what we want (100, which represents the CLM4 value.).
src.clm/atm2lndType.F90: Add some additional history fields
src.clm/clm_varpar.F90: nlevurb=5 -> nlevurb=10
src.clm/surfrdMod.F90: Remove read of PFTDATA_MASK

Looking at other plots in #3 it seems like the low value for this parameter is what we want (100, which represents the CLM4 value.).As with others in this series, I'd build on the Sturm case, https://github.com/NCAR/LMWG_dev/discussions/10
starting an AD spinup with initial conditions from the postAD Sturm run setting reseed=.true.
