#79 versus #78 diagnostics posted above.

did we do this one wrong, @slevis-lmwg ? Looks like the dmax60 run decreased annual LH fluxes, which increased FSDS over much of the mid-latitudes during summer

I changed d_max from 15 (default value in ctsm60_params.c240822.nc) to 60 in /glade/u/home/slevis/paramfiles/ctsm60_params_dmax60.c240822.nc

I have not looked at this section of code before. It seems that higher d_max would increase dsl, which would increase soilresis and (I'm assuming) decrease FGEV (which is what we see). FCTR and FCEV have increased some but not enough to compensate.

@wwieder let me know if you would like me to try a different d_max value.

I think that was maybe my fault in that I incorrectly stated that an increase in d_max would increase ET. I would try reducing d_max from the default and try again.

@dlawrenncar @wwieder
I will try d_max = 10 based on Table S1 in Zarakas et al. 2024
