Directory for coupler history data mode (used when DATM_MODE is CPLHIST)
May also be used if any of these are set to cplhist: DATM_PRESAERO, DATM_NDEP, DATM_CO2_TSERIES, DATM_PRESO3, or DATM_TOPO
NOTE: This needs to be the full directory path where the CPLHIST files are stored, including the subdirectory for the CASENAME (that can be set using $DATM_CPLHIST_CASE)
We thus recommend that $DATM_CPLHIST_CASE be used in here to specify that case subdirectory.
This allows the DATM_CPLHIST_DIR to be set for all your CPLHIST datafiles, and you only need to modify $DATM_CPLHIST_CASE to point to a different CASE.
For example, to use the CPLHIST data generated from a case that you ran do this:
./xmlchange DATM_CPLHIST_DIR='$CIME_OUTPUT_ROOT/archive/$DATM_CPLHIST_CASE/cpl/hist'
Which will then use the CPL history files in your archive directory for the case that created the desired CPLHIST data.
