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: " "
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: " "
Required: no, but highly recommended
Description: This is a short text string which is included in output files
to help identify the model run.
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.
rest_pfile
Type: character(len=256)
Default: "./rpointer"
Required: no
Description: This is the complete path and name of the restart "pointer
file." This must include an existing, NFS mounted directory. All run
types will update this file (and create it, if necessary), but only a
continuation runs requires that this file exists prior to the start of
the run.
rest_bfile
Type: character(len=256)
Default: "null"
Required: required if rest_type = "branch", ignored otherwise.
Description: This is the file name of the "branch file" (the IC data file).
Note that a prefix like "mss:" is used to indicate a file archival device,
Valid prefix options are:
* "null:" indicates no retrieval -- associated data file has been
prepositioned into the current working directory.
* "cp:" or no-prefix indicates a normal unix file copy to an NFS mounted
file system.
* "mss:" indicates retrieval from NCAR's Mass Storage System (MSS)
rest_date
Type: integer
Default: 00010101 (year 1, month 1, day 1, encoded yyyymmdd)
Required: no (ignored for "continuation" runs, optional for others).
Description: This is the restart date.
* On startup and hybrid runs, rest_date is the initial date of the
simulation.
* On branch runs, if rest_date > 0, it will over-ride the date contained
in the rest_bfile IC restart file. Otherwise the date from the
rest_bfile data file is used.
* On continuation runs rest_date is not used (the date contained in the IC
file is used).
ncpl
Type: integer
Default: 24
Required: no
Description: This specifies how many times per day the model communicates
(exchanges data) with the coupler.
data_file
Type: character(len=256)
Default: "null"
Required: yes
Description: This specifies the name of the netCDF input file in which ice
fraction data is found. The directory in which this file is found is
specified by the data_dir namelist variable.
data_dir
Type: character(len=256)
Default: "null:"
Required: no
Description:
The specifies the directory in which the input ice fraction data file
is found (see the data_file namelist variable). Valid prefix options are:
* "null:" indicates no archival -- associated data file has been
prepositioned into the current working directory.
* "cp:" or no-prefix indicates a normal unix file copy to an NFS mounted
file system.
* "mss:" indicates retrieval from NCAR's Mass Storage System (MSS)
Eg. data_dir = "cp:/usr/jdoe/" requests a local copy from the directory
/usr/jdoe.
domain_file
Type: character(len=256)
Default: "null"
Required: yes
Description: This specifies the name of the netCDF file in which input
domain specification data is found. The directory in which this file is
found is specified by the domain_dir namelist variable.
domain_dir
Type: character(len=256)
Default: "null:"
Required: no
Description:
The specifies the directory in which the input domain specification data
file is found (see the domain_file namelist variable). Note that a prefix
like "null:" is used to indicate a file archival device.
Valid prefix options are:
* "null:" indicates no retrieval -- associated data file has been
prepositioned into the current working directory.
* "cp:" or no-prefix indicates a normal unix file copy from an NFS
mounted file system.
* "mss:" indicates retrieval from NCAR's Mass Storage System (MSS)
Eg. data_dir = "cp:/usr/jdoe/" requests a local copy from the directory
/usr/jdoe.
flux_acc
Type: integer boolean
Default: 0 (false/off)
Required: no
Description: If activated, the dice model accumulates ice formed in the
ocean component -- this a flux field sent from the ocean to the ice. This
accumulated ice can subsequently be melted back into the ocean component
if and when there is sufficient melting potential. Melting potential is
also a field sent from the ocean to the ice component.
flux_swpf
Type: real
Default: 0.0
Required: no
Description: This is the "short-wave penetrating factor". This is the
fraction of net solar absorbed by the ice model the penetrates through
the ice and ends up being absorbed into the ocean below.
mss_dir
Type: character(len=256)
Default: "null"
Required: yes
Description: This is a file archival directory name including the
specification of an archival device. Restart and history files go into
this directory. For continuation runs, the initial condition restart file
must also be in this directory. A "prefix" is all the characters up to
and including the first occurrence of ":". The prefix of the file
indicates a storage device. Valid prefix options are:
* "cp:" or no-prefix indicates a normal unix file copy to an NFS mounted
file system.
* "mss:" indicates archival onto NCAR's Mass Storage System (MSS)
* "null:" indicates no archival of any sort.
Some of the following mss_xxx options are only meaningful when the
archival device is NCAR's MSS. With code modification, more archival
devices could be implemented (eg. "hpss:").
mss_rtpd
Type: integer
Default: 365
Required: no
Description: Retention period, in days, for data files sent to the MSS.
See the msrcp man pages at NCAR for more details.
mss_pass
Type: character(len=16)
Default: " " (no password)
Required: no
Description: msrcp write password string for files sent to the MSS.
Read passwords are not an option with the Coupler.
See the msrcp man pages at NCAR for more details.
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
