Parameter Name Default Value Data Type Group CASEROOT File Valid Values Description
COMP_ATM datm char case_comp env_case.xml ['datm']
Name of atmospheric component
DATM_MODE CORE2_NYF char run_component_datm env_run.xml ['CORE2_NYF', 'CORE2_IAF', 'CLM_QIAN', 'CLM_QIAN_WISO', 'CLM1PT', 'CLMCRUNCEP', 'CLMCRUNCEPv7', 'CLMGSWP3v1', 'CPLHIST', 'CORE_IAF_JRA']
Mode for data atmosphere component.
      CORE2_NYF (CORE2 normal year forcing) are modes used in forcing prognostic ocean/sea-ice components.
      CLM_QIAN, CLMCRUNCEP, CLMCRUNCEPv7, CLMGSWP3v1 and CLM1PT are modes using observational data for forcing prognostic land components.
DATM_PRESAERO clim_2000 char run_component_datm env_run.xml ['none', 'clim_1850', 'clim_2000', 'clim_2010', 'trans_1850-2000', 'SSP1-1.9', 'SSP1-2.6', 'SSP2-4.5', 'SSP3-7.0', 'SSP4-3.4', 'SSP4-6.0', 'SSP5-3.4', 'SSP5-8.5', 'cplhist']
DATM prescribed aerosol forcing
DATM_TOPO observed char run_component_datm env_run.xml ['none', 'observed', 'cplhist']
DATM surface topography forcing
DATM_CO2_TSERIES none char run_component_datm env_run.xml ['none', '20tr', '20tr.latbnd', 'SSP1-1.9', 'SSP1-2.6', 'SSP2-4.5', 'SSP3-7.0', 'SSP4-3.4', 'SSP4-6.0', 'SSP5-3.4', 'SSP5-8.5', 'SSP1-1.9.latbnd', 'SSP1-2.6.latbnd', 'SSP2-4.5.latbnd', 'SSP3-7.0.latbnd', 'SSP4-3.4.latbnd', 'SSP4-6.0.latbnd', 'SSP5-3.4.latbnd', 'SSP5-8.5.latbnd']
DATM CO2 time series
DATM_CPLHIST_DOMAIN_FILE null char run_component_datm env_run.xml []
      Full pathname for domain file for datm when DATM_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.
    
DATM_CPLHIST_DIR UNSET char run_component_datm env_run.xml []
directory for coupler history data mode (only used for when DATM_MODE is CPLHIST)
DATM_CPLHIST_CASE UNSET char run_component_datm env_run.xml []
case name used to determine stream filenames when DATM_MODE is CPLHIST
DATM_CPLHIST_YR_ALIGN -999 integer run_component_datm env_run.xml []
      Simulation year corresponding to DATM_CPLHIST_YR_START (only used
      when DATM_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 DATM_CPLHIST_YR_START. Another
      use case is to align the calendar of transient forcing with the
      model calendar. For example, setting
      DATM_CPLHIST_YR_ALIGN=DATM_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.
    
DATM_CPLHIST_YR_START -999 integer run_component_datm env_run.xml []
starting year to loop data over (only used when DATM_MODE is CPLHIST)
DATM_CPLHIST_YR_END -999 integer run_component_datm env_run.xml []
ending year to loop data over (only used when DATM_MODE is CPLHIST)
DATM_CLMNCEP_YR_ALIGN 1 integer run_component_datm env_run.xml []
year align
DATM_CLMNCEP_YR_START 2004 integer run_component_datm env_run.xml []
starting year to loop data over
DATM_CLMNCEP_YR_END 2004 integer run_component_datm env_run.xml []
ending year to loop data over
