General Questions

  • On which granularities are DOI data references provided?
    There are two granularities (see also WIP White Paper ):
    1. model/MIP: Data reference for all data provided from an institution with a specific model to a MIP
    2. experiment: Data reference for all data provided from an institution with a specific model to an experiment (use of API required!)
  • One of my experiment belongs to two MIPs. For which DRS should I provide data reference details?
    The DOIs are connected to the dataset_id of the ESGF, which is based on the DRS. Thus please provide the data reference for the MIP, which you use in the directory structure (DRS).
  • How do I provide author lists and other information for the experiments, which are not visible in the GUI?
    Please use the API for any metadata changes for experiment entries (see Best Practices for details). I can make specific entries visible for you in the GUI. I recommend to use the API for maintaining the information on experiment granularity.
  • Will changes of author lists on the model/MIP granularity be changed on experiment granularity as well?
    No. The reason is that you should remain in full control of the author lists and be able to have different author lists for model/MIPs and related experiments. Changes on experiment granularity should be done using the API. I can also make specific entries visible for you in the GUI.
    Note: For missing author lists on experiment granularity, the author lists provided on the related MIP/model entry are used as author list for the related experiments after the DOI on MIP/model gets registered i.e. after you have published your data in ESGF. No existing author lists are overwritten by us.
  • Will there be any DOIs registered after 31 January 2021?
    Yes, that will continue on both granularities. That is why you are asked to provide author lists for all data, which you plan to publish in future. Entries in the citation database are related to your registration at: . You might want to check your registration in source_id for completeness.
  • Does the publication of new dataset versions or additional ensemble data have an effect on the DOIs?
    No, the CMIP6 citation follows an evolving data approach. That means that it is possible to add data to a data collection baring a DOI. To specify the data used when citing your data, please include the (ESGF) data version in your data reference, replacing the placeholder 'Version YYYYMMDD in the citation information provided on the related DOI landing page.

  • I cannot find the entries for the experiments in the GUI. What should I do?
    The number of experiments might get too many for a GUI application. Therefore please use the API instead (see: Best Practices)
  • Can I update 'lists of persons' e.g. author lists?
    No, that is not possible to keep a record of all previously used author lists. Please do the following:
    • edit+modify the 'list of persons' and store it under a new name
    • goto step 3 and exchange the 'list of persons' for each entry


Landing Page

  • What does the version YYYYMMDD in the data reference on the landing page mean?
    This specifies the latest ESGF dataset version used when the evolving data collection is referenced (see also footnote on the landing page).
    As our CMIP6 citations are assigned for a data collection of evolving data (including all versions), a data user citing the data needs to specify the ESGF dataset version to specify the data subset used e.g. in an article. ESGF CoG supports filtering for version ranges in the "More Search Options" section.
