CESM2.1.3 DROF2.1 CASEROOT Variable Definitions

Name of rof component

DROF mode. Values are CPLHIST, *_RX1, and NULL. In *_RX1 mode,
    observational climatological or interannual
    1-degree runoff data is used. In CPLHIST mode, runoff
    data from a previous model run is read in. In NULL mode, the runoff
    data is set to zero. In CPLHIST mode, runoff forcing data from a previous
    model run is output by the coupler and read in by the data rof
    model. In NULL mode, runoff forcing is set to zero and not used. The
    default is DIATREN_ANN_RX1.

      Full pathname for domain file for drof when DROF_MODE is
      CPLHIST.  NOTE: if this is set to 'null' (the default), then
      domain information is read in from the first coupler history
      file in the target stream and it is assumed that the first
      coupler stream file that is pointed to contains the domain
      information for that stream.
    

directory for coupler history data mode (only used when DROF_MODE is CPLHIST mode)

case name for coupler history data mode (only used when DROF_MODE is CPLHIST mode)

      Simulation year corresponding to DROF_CPLHIST_YR_START (only used
      when DROF_MODE is CPLHIST). A common usage is to set this to
      RUN_STARTDATE. With this setting, the forcing in the first year of
      the run will be the forcing of year DROF_CPLHIST_YR_START. Another
      use case is to align the calendar of transient forcing with the
      model calendar. For example, setting
      DROF_CPLHIST_YR_ALIGN=DROF_CPLHIST_YR_START will lead to the
      forcing calendar being the same as the model calendar. The forcing
      for a given model year would be the forcing of the same year. This
      would be appropriate in transient runs where the model calendar is
      setup to span the same year range as the forcing data.
