The prerequisite is to have eccodes python 3 modules available in the system. The tool itself consist of two python scripts attached to this page:
...
The set up file contains mostly a python dictionary with the allowed ranges for parameters. These ranges can be easily tuned and can be specific for specific selection of metadata if needed (e.g. MARS class, level type etc).
Please be aware that this tool is not part of ecCodes any package yet as is still under development. For example some code refactoring or performance optimisation is might be needed. ![Work_In_Progress.png](/plugins/servlet/confluence/placeholder/unknown-attachment?locale=en_GB&version=2)
