3 Namelist

The model reads an input namelist from stdin at runtime. 
Following is a list and description of available namelist input parameters.

case_name
     Type: character(len=16)
     Default: "null"
     Required: no, but highly recommended
     Description: This is the case name text string that appears in output files
     to help identify the model run.  

case_desc
     Type: character(len=64)
     Default: "null"
     Required: no, but highly recommended
     Description: This is a short text string (typically less than 80 chars) 
     which is included in output files to help identify the model run.

data_type[1...3]
     Type: character(len=16)
     Default: "fabricate"
     Required: no
     Description: This specifies the type of data to be used for state,
     precipitation, and radiation fields, respectively.  Examples:
     (1) data_type = "fabricate" => make domain data and use constant fields;
         no data is read in.  NOTE:  If any or all of the data_type elements are
         set to "fabricate", all fields are fabricated.
     (2) data_type = "NCEP" => read in NCEP data.
     (3) data_type = "CCM" => read in data from an active atmosphere simulation.

data_dir[1...3]
     Type: character(len=256)
     Default: "null:"
     Required: yes
     Description: This specifies where the data input file sequences
     are found for state, precipitation, and radiation data files, respectively.
     Examples:
     (1) data_dir = "null:/whatever " => the "null:" prefix indicates that the
         data has already been pre-positioned in the exectution directory.
     (2) data_dir = "mss:/JDOE/data " => look for input data on NCAR's
          Mass Storage System archival device.
     (3) data_dir = "cp:~jdoe/data " => look for input data in user jdoe's
         home directory in the data subdirectory.

data_year0[1...3]     
     Type: integer
     Default: 1
     Required: yes (unless the data year happens to be 1)
     Description: the 1st year in the state, precipitation, and radiation
     data files, respectively, e.g. 1985.

data_oyear[1...3]     
     Type: integer
     Default: 1
     Required: yes
     Description: the simulation year matched to year0 for the state, 
     precipitation, and radiation data files, respectively, e.g. 1.

data_nyear[1...3]     
     Type: integer
     Default: 1
     Required: no (unless you want to cycle thru more than one year)
     Description: the number of years in the sequence for the state, 
     precipitation, and radiation files, respectively, e.g. 2.

rest_type
     Type: character(len=16)
     Default: "continue"
     Required: no (but default is of limited usefulness)
     Description: This selects the run type.  
     Valid choices are: "startup", "hybrid", "continue", or "branch".  
     Selecting "branch" makes rest_bfile a required input.

ncpl
     Type: integer
     Default: 24
     Required: no
     Description: This specifies how many times per day the model
     communicates (exchanges data) with the coupler.


flux_albfb
     Type: integer boolean (0 <=> false)
     Default: 0 
     Required: no
     Description: If flux_albfb = true, then albedo feedback is activated.

info_dbug
     Type: integer
     Default: 1
     Required: no
     Description: Debugging information level: 0, 1, 2, or 3.
     * 0 => write the least amount of debugging information to stdout
     * 1 => write a  small  amount of debugging information to stdout
     * 2 => write a  medium amount of debugging information to stdout
     * 3 => write a  large  amount of debugging information to stdout
