(a) NOTE: 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. Instead, it is just an indexing label that gets changed once per year.
NOTE
Currently these data are only available using CDS API and may appear as (partially or totally) unavailable in the CDS interactive forms
Nominal Start Dates
For systems with lagged ensembles having multiple start dates, the "nominal" start date is assigned as follows:
Météo-France:
- Forecasts/Hindcasts: nominal month M includes the members initialised in the last weeks of month M-1 and on the 1st of month M
GloSea5-GC2:
- Hindcasts: nominal month M includes the members initialised on the 1st of month M and on the 25th, 17th and 9th of month M-1
- Forecasts: nominal month M includes the members initialised on the 1st of month M and all available members with start dates back to, and including, the 2nd of month M-1
