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

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’.
