Warning

Please note:

  • In the next release we will deprecate the following tools:
    • grib_merge
    • gg_sub_area_check
    • big2gribex
  • In the near future,
official support of sub-hourly GRIB2 data will be released.
This will have an impact on users of ecCodes who currently produce sub-hourly GRIB2 data.
We strongly encourage you to contact us ahead of time so that we can help you adapt to the changes that this release will bring.
  • the contents of the "definitions/grib2" directory will be grouped into sub-directories.
    This could affect users who have their own customised definitions.
