NOTES
(1) For each real-time forecast start date, the associated hindcast data is produced and made available through the CDS at least one month in advance. The details about data availability can be found in "Summary of available data" page.
...
(3) Despite being produced in a lagged mode, the data from Météo-France this forecasting systems system is currently encoded and provided in CDS as if all the members were initialized on the 1st.
...
(6) Details of the complete list of start dates are provided in the description of CPS2 CPS3 system, section 6. Other relevant information.
(7) ECCC contribution, CanSIPSv2CanSIPSv3.10, is a multi-system composed of two independent forecasting systems.
(8) At present, no hindcast data is available for start dates before 1993.

For these forecasting systems, a unique value of the keyword "system" is assigned trying to map as close as possible the version numbering used by the forecasting centres. Specifically:

(*) This model_id
tag is used internally in some parts of the CDS infrastructure to label the seasonal forecast data. In particular data which is archived on netCDF format will use this labelling. Currently this only applies to ocean variables contained in the seasonal-monthly-ocean
dataset.
(a) 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)
Systems producing their hindcasts on-the-fly
...
The only producing centre following this approach in this period was the UK MetOffice, and the increments on the value of 'system' were introduced on the May nominal start date each year. Specifically:
Forecasting centre | Forecasting system name | Real-time forecast nominal start dates | CDS 'system' value | CDS 'model_id' (*) |
---|---|---|---|---|
UK MetOffice | GloSea5-GC2 | September 2017 to April 2018 | 12 | HadGEM3-GC2.0-v20150825 |

GloSea5-GC2-LI | May 2019 to April 2020 | 14 | HadGEM3-GC2.0-v20190305 | |

(*) This model_id
tag is used internally in some parts of the CDS infrastructure to label the seasonal forecast data. In particular data which is archived on netCDF format will use this labelling. Currently this only applies to ocean variables contained in the seasonal-monthly-ocean
dataset.
After March 2021
With the start of operations of MetOffice GloSea6 forecasting system, a new numeric labelling paradigm has been introduced with two main aims: on one hand, to keep the incremental labelling when needed, and on the other hand, make more transparent and user-friendly the mapping between different versions of the forecasting system and that 'system' keyword.
...
The following table lists the values of 'system' keyword used in the CDS for on-the-fly hindcasts systems:
Forecasting centre | Forecasting system name | Real-time forecast nominal start dates | CDS 'system' value | CDS 'model_id' (*) |
---|---|---|---|---|
UK MetOffice | GloSea6 |

2021 to February 2022 | 600 | HadGEM3-GC3.2-v20200929 |
