Please see the recent announcements in the C3S seasonal [documentation pages](https://confluence.ecmwf.int/display/CKB/Announcements) regarding the discontinuation of the current operational systems from Environment and Climate Change Canada (ECCC), and the planned availability of data and graphical products from their new systems.

Please also note that the graphical products for DWD are missing for July 2024, as detailed in a further announcement, as there are issues with the forecast data received: [Announcements - Copernicus Knowledge Base - ECMWF Confluence Wiki](https://confluence.ecmwf.int/display/CKB/Announcements) In particular, initial examination points to the 22nd member of the ensemble (in the order archived) having been started from wrong initial conditions; at present, there is no guarantee that the other members are ‘correct’.
