Incomplete set of start dates

In the next table it is shown what nominal start dates are available from those forecast system which don't have a complete set of 12 nominal start dates available on the CDS.

Such unavailability is due to different reasons: some forecast systems produce their hindcasts on-the-fly close to the time when it is released the real-time forecast they go with; some others have been recently introduced in production and not all nominal star dates have been either run by their producing centre or processed and archived by C3S; and also there is a small list of forecast systems that were discontinued before all their start dates were processed by C3S.

(a)For the Met Office contribution, due to the production of hindcasts "on-the-fly", the CDS keyword 'system' does not have the same meaning as for the other contributors. More details here.
(b) Due to technical reasons, a new version of ECMWF SEAS5 data has been created using the keyword system=51. See details on Announcements (date 12/October/2022)
(c) Hindcast data for January 1993 is not available from MetOffice forecast systems (see "known issue" G4 on the data gaps section)
