Changes to ECMWF NWP data filenaming

On 11 June, ECMWF will change the filenaming of their NWP data; part of these data are distributed on EUMETCast.

The filenaming changes:

  • The files *10fgg20* will be renamed to *10fgg25*. The content of these files will remain unchanged parameter-wise. They will be renamed to *10fgg25* as they already contain the parameter 10fgg25.
  • There will be a 24 hour shift in the part of the filename that carries the step information. This change will apply to all *10fgg* files.


Current filename:

Sample data with the new filenaming are available on our FTP server

ECMWF will be releasing the new filename products on 11 June with the 12:00 UTC run.

This cycle coincides with the release of their new model 46r1.
