The reanalysis data of COSMO-REA6, COSMO-REA2 and COSMO-ENS-REA12 may be used without any restrictions, provided that the source is indicated as stated in the Terms of Use (German, courtesy translation to English). Please note, that only the German document "Terms of Use" shall be legally binding.
The full model output comprises a set of 150 variables (2D and 3D fields). A full list of variables will soon be provided.
As of May 2021 a subset of often requested parameters is available for direct download from the opendata-FTP server at DWD (https://opendata.dwd.de/climate_environment/REA/COSMO_REA6/).
Data is available in hourly, daily or monthly aggregation.
