(*) 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 Summary of available data page (footnotes "Real-time forecasts" table)
