For systems with lagged ensembles having multiple start dates, the "nominal" start date is assigned as follows: Météo-France (all systems):
NOTE: Even though the different members of all Météo-France forecasting system ensembles are initialized using a lagged approach, the real start dates are not revealed to the users, so all members are encoded as if they were initialized on the 1st of the month GloSea5-GC2:
