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 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.

(*) 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)
