A comprehensive evaluation report of the 47r1 e-suite has been prepared documenting all the changes and their impact on the forecasts. Noteworthy improvements w.r.t to the current o-suite cycle 46r1 are:
There are no new or discontinued parameters in the disseminated data compared to 46r1.
The CAMS operational FTP server (ECPDS) currently serves the most recent 3 days of test data 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) are provided as individual files in the 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 1 October 2019 onwards directly on MARS or through our WebAPI.
