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.
ncpl
Type: integer
Default: 24
Required: no
Description: This specifies how many times per day the model
communicates (exchanges data) with the coupler.
data_dir
Type: character(len=256)
Default: "null:"
Required: yes
Description: This specifies where the land data input file sequence
is found. Examples:
(1) data_dir = "cp:~jdoe/data " => look for input data in user djoe's
home directory in the data subdirectory.
(2) data_dir = "mss:/JDOE/data " => look for input data on NCAR's
Mass Storage System archival device.
(3) data_dir = "null:/whatever " => the "null:" prefix indicates that the
data has already been pre-positioned in the exectution directory.
data_fname
Type: character(len=256)
Default: "null"
Required: yes
Description: This specifies file names of the input data files. The data
files are assumed to contain one year's worth of data -- 365 daily averages.
The file name can be any valid unix file name. This is a template file
name, that is, somewhere in the file name must be the text substring "yyyy"
which will be replaced by a specific year to create the actual file name.
For example, if data_fname = "f20.005.cam2.h1.yyyy-01-01-00000.nc" and datm
model needs data for year 2002, it will construct the file name
"f20.005.cam2.h1.2002-01-01-00000.nc", and look for this file in the
directory data_dir described above.
data_year0
Type: integer
Default: 1
Required: yes
Description: This specifies the first year in the input atmosphere data
file sequence.
data_nyear
Type: integer
Default: 1
Required: no
Description: This specifies the number of years in the input atmosphere
data file sequence.
data_oyear
Type: integer
Default: 1
Required: no
Description: This specifies the "offset year" for the input atmosphere
data file sequence. The data file for data_year0 will coincide with the
simulation year data_oyear.
mss_rmlf
Type: integer boolean (0 <=> false)
Default: 0
Required: no
Description: This specifies whether to remove the local copy of an
input atmosphere data file after it has been read in by the model.
Iff mss_rmlf = 0, then the model will not remove the local file.
flux_albfb
Type: integer boolean (0 <=> false)
Default: 0
Required: no
Description: If flux_albfb = true, then albedo feedback is activated.
flux_swfact
Type: real
Default: 1.0
Required: no
Description: This factor is applied to all shortwave fields.
This can be used to arbitrarily increase or decrease shortwave values.
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
