Please note:

  • In the next release we will deprecate the following tools:
    • grib_merge
    • gg_sub_area_check
    • big2gribex
  • In the near future, the contents of the "definitions/grib2" directory will be grouped into sub-directories.
    This could affect users who have their own customised definitions.

Please note: There is a new webpage for the Migration to GRIB2: Migration to GRIB2
This webpage also includes a section where changes in the parameter encodings for the coming ecCodes versions are documented: Changes in the parameter encodings
