Warning

Please note :We are aiming to add official support for sub-hourly GRIB2 data in the next release (v2.34.0).
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.

 

Warning

Please note some important changes in this release (v2.34.0) of ecCodes:

  • The key "levtype" is now read-only (for Support for sub-hourly data in GRIB edition 2). Please use "typeOfLevel" to set fixed surface types
  • The key "validityTime" now has 4 characters as a string (like dataTime). This affects the output of commands like "grib_ls -n time"
  • . For more details, see here


Info

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
