The CAMS operational ECMWF data portal (aux.ecmwf.int; SFTP/FTP/HTTPS data access) will serve the most recent 3 days of test data, once the e-suite is running in near-real-time, in the directories "/DATA/CAMS_GLOBAL_TEST" and "/DATA/CAMS_EUROPE_BC_TEST" for global and regional boundary condition data, respectively. In addition, surface level fields (model level 137) will be provided as individual files in the "/DATA/CAMS_GLOBAL_ADDITIONAL_TEST" directory. Users wanting to access the output from the current test system for a longer period can access the data from <> 05-2025 onwards directly on MARS or through the Atmosphere Data Store. More details can be found here: Accessing CAMS 50r1 test data. |
