wgrib2: -import_bin, -import_ieee, -import_text, -import_grib

Introduction

wgrib2 will decode the grib file when necessary and save the decoded grid point values in a floating point array (DATA). The -import options read grid point values from a specified file and replace the values of DATA. The -import options are the means that wgrib2 creates new grib files (read existing grib file, import data, change metadata, write new grib file).

Note that the import functions will the precision of the grib writing (new files) to the default (12 bits which can be changed).

Usage

-import_bin data.txt              .. a binary (native format floating point) file
                                       -header and -no_header affect the format
-import_ieee data.ieee            .. a big-endian 32-bit ieee file
                                       -header and -no_header affect the format
-import_text data.txt		  .. a text file
                                       -header and -no_header affect the format
-import_grib data.grb2            .. a grib2 file, only -g2clib 0 and -g2clib 1 supported
                                       conversion to we:sn and we:ns is done

Note: the bin/ieee/text/grib formats are the same as from the output options
  -bin, -ieee, -text and -grib/-grib_out  with the exception that little_endian ieee
  is not supported.

Many scripts use the import option.

  1. g2grb.gs - grads script a field to grib2
  2. grb1to2.pl - grib1 to grib2 conversion
  3. cmp_grib2_grib2.sh - compare two grib2 files
  4. cmp_grib1_grib2.sh - compare two grib1 and grib2 files
