ext_frc_specifier chem_inparm cam_chem char*256(1000) ['any char']
List of full pathnames of elevated emission (or external chemical forcings) datasets.

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).

List of full pathnames of surface emission datasets.

The chemistry package reads in emission data from a set of netcdf files in
units of "molecules/cm2/s".  Each tracer species emissions is read from its
own file as directed by the namelist variable srf_emis_specifier.  The
srf_emis_specifier variable tells the model which species have emissions
and the file path for the corresponding species.  That is, the
srf_emis_specifier variable is set something like:

 srf_emis_specifier = 'CH4 -> /path/emis.ch4.nc',
                      'CO  -> /path/emis.co.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.

arithmetic (standard for geopk16) or method 2 when utilizing the

two subcycles of a timestep, method 0 is automatically used; see

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", ...,

        FORCING:
        --------
        Nudging tendencies are applied as a relaxation force between the current
        model state values and target state values derived from the avalilable
        analyses. The form of the target values is selected by the 'Nudge_Force_Opt'
        option, the timescale of the forcing is determined from the given 
        'Nudge_TimeScale_Opt', and the nudging strength Alpha=[0.,1.] for each 
        variable is specified by the 'Nudge_Xcoef' values. Where X={U,V,T,Q,PS}
 
               F_nudge = Alpha*((Target-Model(t_curr))/TimeScale
 
        WINDOWING:
        ----------
        The region of applied nudging can be limited using Horizontal/Vertical 
        window functions that are constructed using a parameterization of the 
        Heaviside step function. 
    
        The Heaviside window function is the product of separate horizonal and vertical 
        windows that are controled via 12 parameters:
    
            Nudge_Hwin_lat0:     Specify the horizontal center of the window in degrees. 
            Nudge_Hwin_lon0:     The longitude must be in the range [0,360] and the 
                                 latitude should be [-90,+90].
            Nudge_Hwin_latWidth: Specify the lat and lon widths of the window as positive 
            Nudge_Hwin_lonWidth: values in degrees.Setting a width to a large value (e.g. 999) 
                                 renders the window a constant in that direction.
            Nudge_Hwin_latDelta: Controls the sharpness of the window transition with a 
            Nudge_Hwin_lonDelta: length in degrees. Small non-zero values yeild a step 
                                 function while a large value yeilds a smoother transition.
            Nudge_Hwin_Invert  : A logical flag used to invert the horizontal window function 
                                 to get its compliment.(e.g. to nudge outside a given window).
    
            Nudge_Vwin_Lindex:   In the vertical, the window is specified in terms of model 
            Nudge_Vwin_Ldelta:   level indcies. The High and Low transition levels should 
            Nudge_Vwin_Hindex:   range from [0,(NLEV+1)]. The transition lengths are also 
            Nudge_Vwin_Hdelta:   specified in terms of model indices. For a window function 
                                 constant in the vertical, the Low index should be set to 0,
                                 the High index should be set to (NLEV+1), and the transition 
                                 lengths should be set to 0.001 
            Nudge_Vwin_Invert  : A logical flag used to invert the vertical window function 
                                 to get its compliment.

Maximum master length scale designed to address issues in diag_TKE outside the

In order not to disturb turbulence characteristics in the lower troposphere,
this should be set at least larger than a few km. However, this does not
significantly improve the values outside of the boundary layer. Smaller values
make some improvement, but it is also noisy. Better results are seen using
