With the implementation of IFS Cycle 50r2 (currently scheduled for Q1 2027), use of the LEGACY filenaming convention for IFS real-time products delivery via the ECMWF Production Data Store (ECPDS) will be discontinued.
We advise that you review how this change will affect your activities and plan accordingly.
Further information is available on the File naming convention and format for real-time data page.
If you have any issues, concerns or feedback, we encourage you to contact us via the ECMWF Support Portal.
