grib_copy examples

  1. To copy only the pressure levels from a file

    >> grib_copy -w levtype=pl ../data/tigge_pf_ecmwf.grib2 out.grib
  2. To copy only the fields that are not on pressure levels from a file

    >> grib_copy -w levtype!=pl ../data/tigge_pf_ecmwf.grib2 out.grib
  3. A grib_file with multi field messages can be converted in single field messageswith a simple grib_copy.

    >> grib_copy multi.grib simple.grib
  4. Use the square brackets to insert the value of a keyin the name of the output file.

    >> grib_copy in.grib out_[shortName].grib
