As part of the 50r1 IFS Cycle implementation, the composition of the data production will change. The 'HRES' will be deprecated in concept, but the oper:fc and wave:fc will continue. enfo:cf and waef:cf are going to be stopped. scda and scwv streams will be merged with oper and wave respectively. In addition, the use=bc parameter will be removed from the data requirements.

As a result, the file names associated with the affected streams and requirement blocks in the three current file-naming templates (ECMWF, LEGACY, WMO) will change. The tables below show which filenames will be modified or removed.

1.    Changes for stream=scda and stream=enfo, type=cf/pf

Green: no change in Cycle 50r1
Red: will be removed in Cycle 50r1 (dropped / no longer used)
