MetOffice real-time component is designed to produce a constant number of members each start date (see Description of the C3S seasonal multi-system). In those rare occasions when the MetOffice is not able to produce some of the expected members for a given start date, the affected members will be missing. Instead of re-running precisely those missing members, the MetOffice system schedules the run on a later start date of as many additional members as they were missing. The following table records all the occurrences of this irregularity by listing the dates when some members are missing (and how many of them) and the dates when additional members were produced. | System | Missing members | Additional members |
