Comments

The specifications for this case are identical to those for the b40.20th.track1.1deg.004
case except for the change of tags from ccsm4_0_beta35 to ccsm4_0_beta38.  It should be
noted that a part of the differences in these these two tags is the change in bndtvghg
from:

/fis/cgd/cseg/csm/inputdata/atm/cam/ggas/ghg_hist_1850-2005_c090419a.nc

to

/fis/cgd/cseg/csm/inputdata/atm/cam/ggas/ghg_hist_1765-2005_c091218.nc

Brian Eaton has stated that this is what explains the difference in the history file
outputs between this case and the b40.20th.track1.1deg.004 case.
