The chemistry package reads in elevated emission data from a set of netcdf files in units of "molecules/cm3/s". Each tracer species emissions is read from its own file as directed by the namelist variable ext_frc_specifier. The ext_frc_specifier variable tells the model which species have elevated emissions and the file path for the corresponding species. That is, the ext_frc_specifier variable is set something like: ext_frc_specifier = 'SO2 -> /path/vrt.emis.so2.nc', 'SO4 -> /path/vrt.emis.so4.nc', etc... Each emission file can have more than one source. When the emission are read in the sources are summed to give a total emission field for the corresponding species. The emission can be read in as time series of data, cycle over a given year, or be fixed to a given date. The vertical coordinate in these emissions files should be 'altitude' (km) so that the vertical redistribution to the model layers is done using a mass conserving method. If the vertical coordinate is altitude then data needs to be ordered from the surface to the top (increasing altitude). Default: set by build-namelist. |

npr_yz | spmd_fv_inparm | dyn_fv | integer(4) | ['any integer(4)'] | A four element integer array which specifies the YZ and XY decompositions. The first two elements are the number of Y subdomains and number of Z subdomains in the YZ decomposition. The second two elements are the number of X subdomains and the number of Y subdomains in the XY decomposition. Note that both the X and Y subdomains must contain at least 3 grid points. For example, a grid with 96 latitudes can contain no more than 32 Y subdomains. There is no restriction on the number of grid points (levels) in a Z subdomain, but note that the threading parallelism in the FV dycore is over levels, so for parallel efficiency it is best to have at least the number of levels in each Z subdomain as there are threads available. There are a couple of rough rules of thumb to follow when setting the 2D decompositions. The first is that the number of Y subdomains in the YZ decomposition should be the same as the number of Y subdomains in the XY decomposition (npr_yz(1) == npr_yz(4)). The second is that the total number of YZ subdomains (npr_yz(1)*npr_yz(2)) should equal the total number of XY subdomains (npr_yz(3)*npr_yz(4)).

hfilename_spec | cam_history_nl | history | char*256(10) | ['any char'] |
Array of history filename specifiers. The filenames of up to six history
output files can be controlled via this variable. Filename specifiers give
generic formats for the filenames with specific date and time components,
file series number (0-5), and caseid, filled in when the files are
created. The following strings are expanded when the filename is created:
%c=caseid; %t=file series number (0-5); %y=year (normally 4 digits, more
digits if needed); %m=month; %d=day; %s=seconds into current day; %%=%
symbol. Note that the caseid may be set using the namelist
variable case_name.
For example, for a simulation with caseid="test" and current date and time
of 0000-12-31 0:00UT, a filename specifier of "%c.cam2.h%t.%y-%m.nc" would
expand into "test.cam2.h0.0000-12.nc" for the first history file. The
filename specifier "%c.cam2.h%t.%y-%m-%d-%s.nc" would expand to
"test.cam2.h1.0000-12-31-00000.nc" for the second history file. Spaces are
not allowed in filename specifiers. Although the character "/" is allowed
in the specifier, it will be interpreted as a directory name and the
corresponding directories will have to be created in the model execution
directory (directory given to configure with -cam_exedir option) before
model execution. The first element is for the primary history file which
is output by default as a monthly history file. Entries 2 through 6 are
user specified auxilliary output files.
Defaults: "%c.cam2.h0.%y-%m.nc", "%c.cam2.h1.%y-%m-%d-%s.nc", ...,
"%c.cam2.h5.%y-%m-%d-%s.nc"

List of fields that have fixed upper boundary conditions (temperature and mass mixing ratios) and corresponding data sources. Each entry in this list is of the form: FLD->source where source may be of the following: MSIS - NRL neutral atmosphere empirical model (Mass Spectrometer Incoherent Scatter radar) TGCM - Input file generated by Thermospheric General Circulation Model SNOE - Input file generated from Student Nitric Oxide Explorer satellite observations UBC_FILE - Generalized input file which spans the upper boundary altitude value (mmr|vmr) - Set to a constant value (e.g., 1.2e-6 mmr) These fields can be set to constant values with units of "mmr" (mass mixing ratio) or "vmr" (volume mixing ratio). The upper boundary values of source UBC_FILE are prescribed in the UBC_FILE_path file. Fields of source UBC_FILE may include a CAM constituent name and a file field name separated by ":". Note: Constituents not included in ubc_specifier default to zero flux through the upper boundary. Example: ubc_specifier = 'Q:H2O->UBC_FILE', 'CH4->2.D-10vmr', 'F->1.0D-15mmr', 'HF->1.0D-15mmr', 'T->MSIS', 'H->MSIS', 'N->MSIS','O->MSIS', 'O2->MSIS', 'H2->TGCM', 'NO->SNOE' Default: set by build-namelist |
