NAME

6       gribdump - Decode GRIB products and display as text
7

SYNOPSIS

9       gribdump [-h] [-b] [-p precision] [-e errpath] [-g tabfile] [-q qspecs]
10              [files ...]

DESCRIPTION

13       This program decodes GRIB products (embedded in WMO product  envelopes)
14       on  the  NWS  High-Resolution  Data Service (HRS) feed, writing textual
15       representations of the products or summaries of the products  to  stan‐
16       dard output.
17

OPTIONS

19       -h     Headers  only.  Information from the Product Description Section
20              and Grid Description Section is output, but no data  values  are
21              output.  The default is to output both headers and data values.
22
23       -b     Brief output.  Only one line is output for each product, provid‐
24              ing summary information of the parameter, grid,  model,  levels,
25              time ranges, and other information.
26
27       -p precision
28              Precision used for printing floating-point values, if other than
29              the 7-significant figure default is desired.
30
31       -e errpath
32              If a GRIB product cannot be decoded, perhaps because it is trun‐
33              cated or otherwise corrupted, it is appended to this file.
34
35
36       -g tabfile
37              Use  GRIB-netcdf translation defined in this file. The format of
38              this file is:
39
40       Grib;netCDF;long name               ;units;comments
41        31 ;CI    ;Sea-ice cover           ;none ;(0-1)
42        34 ;SSTK  ;Sea surface temperature ;K    ;
43       151 ;MSL   ;Mean sea-level pressure ;Pa   ;
44       167 ;T2M   ;2 metre temperature     ;K    ;
45

-q qspecs

47Specification for how to expand so-called quasi-regular or thinned grids  into
48rectangular grids.  This argument is a comma-delimited text string that speci‐
49fies the method of interpolation used (currently lin for linear or cub for cu‐
50bic),  and  the latitude and longitude increments in degrees for the resulting
51grid (e.g. dlat=2.5,dlon=5.0).
52

files

54The path name of one or more files of GRIB products  used  as  input.   If  no
55filenames are provided, GRIB products are read from standard input.
56

EXAMPLE

58       The command
59           gribdump -q "lin,dlat=2.5,dlon=5.0" avn-x.wmo
60       will decode and display values for the products in avn-x.wmo If the da‐
61       ta contain quasi-regular grids, they will be expanded to  full  regular
62       grids  on a 2.5 by 5.0 degree grid before being written into the output
63       file.
