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=64) Default: 'null' Required: yes Description: This specifies where the land data input file sequence is found. The data files are assumed to be named "lsmh_yyyy.nc", where yyyy is the four digit year of the data file. 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. data_year0 Type: integer Default: 1 Required: no Description: This specifies the first year in the input lanland data file sequence. data_nyear Type: integer Default: 1 Required: no Description: This specifies the number of years in the input land data file sequence. data_oyear Type: integer Default: 1 Required: no Description: This specifies the "offset year" for the input land data file sequence. The data file for data_year0 will coincide with the simulation year data_oyear. data_aroff Type: character(len=80) Default: "zero" Required: no Description: It is assumed that the dlnd5 data files contain the 19 basins of runoff data that were used in the lsm land model found in CCSM 1.x, and that no new data files exist that were created using newer land models or using the newer 1x1 degree runoff grid scheme found in CCSM 2.0. * data_aroff = "zero", then the runoff sent to the coupler is zero everywhere. * data_aroff = "null", then the runoff data sent to the coupler is the 19 basin runoff data found in the data files * data_aroff = "UserCreatedFile", then the runoff data sent to the coupler is in a user created data file (an "auxiliary" data file). This option is for power-users only. See the source code file called "runoff_aux.F90". data_fix Type: character(len=64) Default: 1 Required: no Description: To conform to the coupled system data field sign convention, it may be necessary to change the sign (+/-) of certain fields found in the input data file sequence. If data_fix = "sign", then the sign is changed for these fields: evaporation, longwave up, sensible heat flux, and latent heat flux. 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
