CMIP6 Data Citation and Long-Term Archival
- cmip6cite.wdc-climate.de -

I. Data Citation / Data References

Motivation and Concept

For the evolving CMIP6 data disseminated by ESGF (Earth System Grid Federation) an early citation reference has been requested by WGCM CMIP6. These data references have to meet the requirements of Force 11’s ‘Joint Declaration of Data Citation Principles’ . The mayor publishers in Earth Sciences have signed the Commitment to Enabling FAIR Data in the Earth, Space, and Environmental Sciences and are changing their author guidelines, accordingly. For the CMIP6 data subset transferred in the long-term archive of the IPCC DDC (Data Distribution Centre) AR6, the established DataCite data publication is planned. The data citations are provided on model/MIP and simulation granularities to meet different citation requirements in literature.

Details of the concept are described in the WIP White Paper .

Information for Data Users

Find Data References (see also blob post at https://cmip6cite.blogspot.com/2020/04/how-to-find-cmip6-data-citations.html):
Core citation information is displayed in the ESGF portal including a link to the landing page with complete citation information. CMIP6 data citations are also discoverable in
Sample Calls:
  1. Data references on experiment (fine) granularity for a given source_id and activity_id:
    http://cera-www.dkrz.de/WDCC/ui/cerasearch/cerarest/cmip6search?mipEra=CMIP6&activityId=CMIP&sourceId=HadGEM3-GC31-MM&granularity=exp
  2. Update data references of request 1. with data references published at or after a given date:
    http://cera-www.dkrz.de/WDCC/ui/cerasearch/cerarest/cmip6search?mipEra=CMIP6&activityId=CMIP&sourceId=HadGEM3-GC31-MM&granularity=exp&gePublicationDate=2020-01-01
  3. Data references on model/MIP (coarse) granularity contributing to an activity_id available at a given snap-shot date:
    http://cera-www.dkrz.de/WDCC/ui/cerasearch/cerarest/cmip6search?mipEra=CMIP6&activityId=ScenarioMIP&granularity=model&lePublicationDate=2020-03-31

Information for Modeling Centers

Information for ESGF Data Node Managers and other infrastructure developers

Available APIs are documented at https://www.wdc-climate.de/ui/cmip-api-docs/. This partly replaces the slightly outdated specification documentation of all technical components of the citation service and the long-term archival in the DDC: http://bit.ly/1XsVOoz [outdated].

Data Node Managers should check the completion of the data reference information. The citation service provides a specific API for this:
https://cera-www.dkrz.de/WDCC/ui/cerasearch/cerarest/cmip6Citations?
Other APIs are provided for machine-access of the CMIP6 data citations.

CMIP6 Data Citation Service Development

User Workflows for the Data Citation Service

The integration of the service in the ESGF was co-ordinated by the ESGF-QCWT (Quality Control Working Team).

Components:

II. CMIP6 Long-Term Archival and IPCC DDC AR6

IPCC DDC AR6 Reference Data Archive (http://www.ipcc-data.org)

The long-term archival in the DDC adds a level of curation and long-term availability to the data according to the TRUST principles (Transparency, Responsibility, User Focus, Sustainability, Technology; Lin et al., 2020, https://doi.org/10.1038/s41597-020-0486-7). This ensures FAIR data remains FAIR. It implements the IPCC FAIR Guidelines (Pirani et al., 2022). Tasks are: Further information:

IPCC DDC support of IPCC AR6 Working Groups and authors

The DDC supports the IPCC authors during the preparation of the AR6 via:
