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
