This directory contains coupler history output that can be used to
drive dlnd in the sno mode - that is, to force a TG compset (dlnd
forcing active GLC).

Notes about the cpl hist forcing files stored in the following
directories:

b.e10.BG1850CN.f09_g16.002_c120808/
b.e10.BG20TRCN.f09_g16.002_c120808/
b.e10.BGRCP85CN.f09_g16.002_c120808/

These directories contain coupler history output from a set of BG
simulations, with CLM's CN model active. These simulations used a
version of CESM roughly equivalent to cesm1_0_3, but with a number of
feature additions and bug fixes relevant to ice sheet simulation.

Most notably, these runs contained a fix for the computation of
surface mass balance over virtual icesheet columns in CLM. 

For full documentation of these runs, see the accompanying file,
run_documentation.txt_c120808.

These runs output cpl history files with daily values of the s2x
fields (one file per year); annual averages were then produced by
running ncra on each file.

b.e10.BG1850CN.f09_g16.002_c120808: This directory contains output
from a preindustrial run, which can be used to spin up CISM with a
preindustrial surface mass balance field.

b.e10.BG20TRCN.f09_g16.002_c120808: This directory contains output
from a transient 20th century run (1850 - 2005). The forcing data here
can be used to force CISM under a transient 20th century scenario. Or,
some or all of these data can be cycled through to spin up CISM under
20th century conditions.

b.e10.BGRCP85CN.f09_g16.002_c120808: This directory contains output
from a RCP8.5 run (2006 - 2100). The forcing data here can be used to
force CISM under a transient RCP8.5 scenario.
