Quality Checks

Technical Quality Control

The CMIP6 technical quality assurance includes 3 different checking blocks: the consistency check of the CMIP6 Citation Service content, the check of the use metadata (from the ESGF index), and the file metadata consistency and data download check. Citation and use metadata are checked against the information, given by the CMIP6 Citation Service and the ESGF index, while the LTA check includes the adjustment of the file based information with the DB based ones.

Citation metadata check (DOI level)

subject entry_type details error level

scientific contact EXP, DSG as in CMIP6 Citation Service error
EGF citation EXP, DSG title, authors, publisher, edition, DOI as in CMIP6 Citation Service error
list of contributors EXP, DSG as in CMIP6 Citation Service error

Use metadata checks

subject entry_type details error level
spatial coverage DSG, DS longitude, latitude, altitude/depth/level as file coverage error
temporal coverage DSG start and end date as file coverage error

Expected keywords are (depending on entry_type):
