Availability of test data from the cycle 48r1 test suites
The CAMS operational FTP server (ECPDS) 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 and GFAS hourly test data (plume model has been updated) GFAS hourly test data will be provided in the "/DATA/CAMS_GFAS_HOURLY_TEST" directory . Users wanting to access the output from the current test system for a longer period can access the data from 1 September 2022 onwards directly on MARS or through our WebAPIthrough . More details can be found here: Accessing CAMS 48r1 test data (draft).
