ANNOTATED WPS NAMELIST
Updated 8/21/08
General: The WRF Preprocessing System has only one namelist. You must fill out the &share ction for each WPS step, but the step-specific information can be filled out just before you run a particular step. Nesting and grib2 options have been excluded. WPS is only ud for real data cas. The entries in black are from namelist.wps.default and the gray entries are additional options.
&share This ction provides variables that are ud by more than one WPS program.
wrf_core = 'ARW', A character string t to either ‘ARW’ or ‘NMM’ that tells WPS which dynamical core the input data are being prepared for. Default value is ‘ARW’.

16_12:00:00', A list of MAX_DOM character strings of the form 'YYYY-MM-DD_HH:mm:ss' specifying the ending UTC date of the simulation for each nest. The end_date variable is an alternate to specifying end_year, end_month, end_day, and end_hour, and if both methods are given for specifying the ending time, the end_date variable will take precedence. No default value. SMOKE requires 25-hour daily files including hourly forecasts.

No default value. io_form_geogrid = 2, The WRF I/O API format that the domain files created by the geogrid program will be written in. Possible options are: 1 for binary; 2 for NetCDF; 3 for GRIB1. When option 1 is given, domain files will have a
suffix of .int; when option 2 is given, domain files will have a suffix of .nc; when option 3 is given, domain files will have a suffix of .gr1. Default value is 2 (NetCDF).

debug_level = 0 An integer value indicating the threshold for nding debugging information to standard output. The uful range for the debugging level is 0 to 1000, with higher values permitting more output to be nt to standard output. Default value is 0.

&geogrid This ction specifies variables that are specific to the geogrid program. Variables in the geogrid ction primarily define the size and location of all model domains, and where the static geographical data are found.
parent_id = 1, 1, A list of MAX_DOM integers specifying, for each nest, the domain number of the nest’s parent; for the coarst domain, parent_id should be t to 1. Default value is 1.
parent_grid_ratio = 1, 3, A list of MAX_DOM integers specifying, for each nest, the nesting ratio rela
tive to the domain’s parent. No default value.
i_parent_start = 1, 31, A list of MAX_DOM integers specifying, for each nest, the x-coordinate of the lower-left corner of the nest in the parent unstaggered grid. For the coarst domain, a value of 1 should be specified. No default value. (unclear whether first entry is 0 or 1--may be ignored if there is no nest--test data ran either way)
j_parent_start = 1, 17, A list of MAX_DOM integers specifying, for each nest, the y-coordinate of the lower-left corner of the nest in the parent unstaggered grid. For the coarst domain, a value of 1 should be specified. No default value. (unclear whether first entry is 0 or 1--may be ignored if there is no nest--test data ran either way)

e_sn = 61, 97, A list of MAX_DOM integers specifying, for each nest, the nest’s full south-north dimension. For nested domains, e_sn must be one greater than an integer multiple of the nest's parent_grid_ratio (i.e., e_sn = n*parent_grid_ratio+1 for some integer n). No default value.

geog_data_res = '10m','2m', A list of MAX_DOM character strings specifying, for each nest, a corresponding resolution of source data to be ud when interpolating static terrestrial data to the nest’s grid. Taking 1 degree of latitude to be about 111km, the 30s data t has a resolution in the south-north direction of about 0.925km, the 2m data t has a resolution of about 1.85km, and so on. It's generally preferable to interpolate from a data t that has a resolution near the model grid resolution, so you might try using GEOG_DATA_RES='10m','5m' for a 30/10 km domain configuration. For each nest, this string should match a string preceding a colon in a rel_path or abs_path specification (e the description of GEOGRID.TBL options) in the GEOGRID.TBL file for each field; if the string does not match any such string in a rel_path or
abs_path specification for a field in GEOGRID.TBL, a
default resolution of data for that field, if one is specified, will be ud. Default value is ‘default’.
dx = 30000, A real value specifying the grid distance in the x-direction where the map scale factor is 1. For ARW, the grid distance is in meters; for NMM, the grid distance is in degrees longitude. Grid distances for nests are determined recursively bad on values specified for parent_grid_ratio. Default value is 10000.
dy = 30000, A real value specifying the nominal grid distance in the y-direction where the map scale factor is 1. For ARW, the grid distance is in meters; for NMM, the grid distance is in degrees longitude. Grid distances for nests are determined recursively bad on values specified for parent_grid_ratio. Default value is 10000.
map_proj = 'lambert', A character string specifying the projection of the simulation domain. For ARW, accepted projections are ‘Lambert’, ‘polar’, and ‘Mercator’; for NMM, a projection of ‘rotated_ll’ must be specified. Default value is ‘Lambert’.
ref_lat = 34.83, A real value specifying the latitude part of a (latitude, longitude) location who (i,j) location in the simulation domain is known. For ARW, ref_lat gives the latitude of the center-point of the coar domain by default (i.e., when ref_x and ref_y are not specified). No default value.
ref_lon = -81.03, A real value specifying the longitude part of a (latitude, longitude) location who (i,
j) location in the simulation domain is known. For ARW, ref_lon gives the longitude of the center-point of the coar domain by default (i.e., when ref_x and ref_y are not specified). West longitudes are negative; the value of ref_lon should be in the range [-180, 180]. No default value.
ref_x = 37.0,A real value specifying the i part of an (i, j) location who (latitude, longitude) location in the simulation domain is known. The (i, j) location is always given with respect to the mass-staggered grid, who dimensions are one less than the dimensions of the unstaggered grid. Default value is (((E_WE-1.)+1.)/2.) = (E_WE/2.).
ref_y = 30.5, A real value specifying the j part of an (i, j) location who (latitude, longitude) location in the simulation domain is known. The (i, j) location is always given with respect to the mass-staggered grid, who dimensions are one less than the dimensions of the unstaggered grid. Default value is (((E_SN-1.)+1.)/2.) = (E_SN/2.).
张说的读音truelat1 = 30.0, A real value specifying, for ARW, the first true latitude for the Lambert conformal conic projection, or the true latitude for the polar stereographic projection. No default value.
truelat2 = 60.0, A real value specifying, for ARW, the cond true latitude for the Lambert conformal conic projection. No default value.
stand_lon = -98.0, A real value specifying, for ARW, the longitude that is parallel with the y-axis in conic and azimuthal projections. No default value.

geog_data_path = '/mmm/urs/wrfhelp/WPS_GEOG' A character string giving the path, either relative or absolute, to the directory where the geographical data directories may be found. This path is the one to which rel_path specifications in the GEOGRID.TBL file are given in relation to. No default value.
opt_geogrid_tbl_path = 'geogrid/' A character string giving the path, either relative or absolute, to the GEOGRID.TBL file. The path should not contain the actual file name, as GEOGRID.TBL is assumed, but should only give the path where this file is located. Default value is ‘./geogrid/’.

&ungrib Currently, this ction contains only two variables, which determine the output format written by ungrib and the name of the output files.
out_format = 'WPS', A character string t either to ‘WPS’, ‘SI’, or ‘MM5’. If t to ‘MM5’, ungrib will write output in the format of the MM5 pregrid program; if t to ‘SI’, ungrib will write output in the for
mat of ; if t to ‘WPS’, ungrib will write data in the WPS intermediate format. WPS is recommended. There a utility that can read “WPS” format called called史浩

/phd/model/wrf2.2.1/WPS/util/src. Default value is ‘WPS’. prefix = 'FILE', A character string that will be ud as the prefix for intermediate-format files created by ungrib; here, prefix refers to the string PREFIX in the filename PREFIX:YYYY-MM-DD_HH. The prefix may contain path information, either relative or absolute, in which ca the intermediate files will be written in the directory specified. This option may be uful to avoid renaming intermediate files if ungrib is to be run on multiple sources of GRIB data. Default value is 'FILE'.
