Publications to be included in the AR6 are published. The question about how to find a CMIP6 data reference comes up more frequently. The data citation recommendation is part of the DOI landing page for each data collection. But how to find that?<br />
<br />
The different options are discussed in this post. A second blog post discusses <a href="https://cmip6cite.blogspot.com/2020/04/how-to-find-cmip6-data-citations_20.html" target="_blank">machine-accessible options</a>.<br />
<br />
<br />
<h4>
1. ESGF CoG</h4>
The best and least time-consuming option is to check the CMIP6 data
citation at the time of data download in the ESGF CoG portal, e.g. <a href="https://esgf-data.dkrz.de/search/cmip6-dkrz/" target="_blank">https://esgf-data.dkrz.de/search/cmip6-dkrz/</a>.<br />
Use 'Show Citation' and follow the provided link to the landing page.<br />

<h4>
2. CMIP6 Citation Service search interface</h4>
In case the CMIP6 data citations were not stored at the time of data
download, the CMIP6 Citation Service offers a dedicated search interface
at: <a class="external" href="http://bit.ly/CMIP6_Citation_Search" target="_blank">http://bit.ly/CMIP6_Citation_Search</a>. A detailed documentation with use cases is available <a href="https://cera-www.dkrz.de/docs/CMIP6_Citation_APEXtool_Docu.pdf" target="_blank">here</a>. <br />
<br />
The result list includes data references for both granularities
offered. For filtering a simple search using the magnifying glass and an advanced search under 'Actions' > 'Filter' are offered. Please choose the appropriate granularity for your use case.
Each result gives the complete data citation recommendation. Results can be exported in csv, html and PDF formats. To reduce the downloaded information, it is possible to hide individual columns, e.g. via 'Actions' > 'Selected Columns'. Please read the 'Actions' > 'Help' for information on further functionalities.<br />

<br />
<br />
<br />
In case a machine readable version of the complete metadata is required, it is possible to make a link to the json formatted metadata visible via: 'Actions' > 'Select Columns'.<br />
<br />
<br />
<h4>
3. DataCite Search interface</h4>
Another source with a complete record of all CMIP6 data citations is DataCite's search interface at <a href="https://search.datacite.org/repositories/dkrz.esgf" target="_blank">https://search.datacite.org/repositories/dkrz.esgf</a>.<br />
The search syntax is not very intuitive. An example search for MPI-M's CMIP6 data is: <a href="https://search.datacite.org/repositories/dkrz.esgf?query=MPI-M" target="_blank">https://search.datacite.org/repositories/dkrz.esgf?query=MPI-M</a>.<br />

<br />
<br />
<h4>
4. Google Dataset Search</h4>
CMIP6 Data Citations appear in <a href="https://datasetsearch.research.google.com/" target="_blank">Google Dataset Search</a> with an unknown delay. Auto-completion supports DRS_ids.<br />

5. FurtherInfoUrl link</h4>
Based on the 'furtherInfoUrl' global attribute provided in each NetCDF file header, the CMIP6 Data Citation information can be accessed via a page hosted by ES-DOC, e.g. <a href="http://furtherinfo.es-doc.org/CMIP6.DKRZ.MPI-ESM1-2-HR.ssp126.none.r1i1p1f1" target="_blank">http://furtherinfo.es-doc.org/CMIP6.DKRZ.MPI-ESM1-2-HR.ssp126.none.r1i1p1f1</a>.<br />

<h4>
6. OpenAIRE's Explore portal</h4>
An alternative to DataCite's Search offers OpenAIRE's Explore portal <a href="https://explore.openaire.eu/">https://explore.openaire.eu</a>. The search functionality of the Explorer is similar to that of DataCite but easier to use. However, a temporal delay has to be taken into account when using this portal, as the CMIP6 Citation information is harvested by OpenAIRE from DKRZ's OAI server. <br />
<br />
To search through CMIP6 data citation information, please use <a href="https://explore.openaire.eu/search/find/datasets?resulthostingdatasource=%22re3data_____::d18674e211f46fb9e49b1d3122a9c01e%7C%7CWorld%20Data%20Center%20for%20Climate%22&keyword=Earth%20System%20Grid%20Federation" target="_blank">this link as entry point</a>.<br />

<br />CMIP6 Citationhttp://www.blogger.com/profile/01293252854812266595noreply@blogger.com0tag:blogger.com,1999:blog-1233518336129246762.post-88255688578200979452019-12-23T01:33:00.000-08:002020-04-20T06:25:14.816-07:00CMIP6 Citation Service in context of data citation principles and IPCC's 6th assessment cycle and its uncertain future<span style="font-family: "arial" , "helvetica" , sans-serif;">The CMIP6 Citation Service as part of the infrastructure for CMIP6 (Coupled Model Intercomparison Project Phase 6) enable the citation of CMIP data for the first time. Data references are planned to compliment paper references in the next IPCC (Intergovernmental Panel on Climate Change) assessment report AR6 (Stockhause et al., 2019). More specific IPCC author guidelines are about to be sent to the authors in early 2020. The goal is twofold:</span><br />
<ul>
<li><span style="font-family: "arial" , "helvetica" , sans-serif;">to improve the transparency of the AR6 by an increased traceability of its key results, and</span></li>
<li><span style="font-family: "arial" , "helvetica" , sans-serif;">to give credit to the providers of source data analysed by the authors.</span></li>
</ul>
<span style="font-family: "arial" , "helvetica" , sans-serif;">The IPCC author guidelines implement the general author guidelines for data citation developed within the 'Enabling FAIR data project' (Stall et al., 2017). Many publishers and repositories have subscribed these guidelines. Apart from FAIR (Findable, Accessible, Interoperable, Reusable), the long-term preservation and curation of the AR6 data in the trusted (TRUST: Transparency, Responsibility, Users, Sustainability, Technology) repository of the IPCC Data Distribution Centre (DDC) is part of IPCC's new author guidance.<br /><br />The CMIP6 Citation Service itself recommends to cite input4MIPs (Durack et al., 2019) data as well as papers underpinning the CMIP6 data.<br /><br />Implementation and maintenance as well as documentation and support for the CMIP6 Citation Service relies on institutional resources and an increasing share of my spare time. As many other infrastructure components for international projects, the service has no substantial nor long-term funding. Thus my institution has to be convinced that investing in the CMIP6 citation service is worthwhile, which requires</span><br />
<ul>
<li><span style="font-family: "arial" , "helvetica" , sans-serif;">usage numbers and</span></li>
<li><span style="font-family: "arial" , "helvetica" , sans-serif;">user stories / feedback.</span></li>
</ul>
<span style="font-family: "arial" , "helvetica" , sans-serif;">Thus, I cordially invite you to leave comment<span style="font-size: small;">s to shar</span>e your opinion about the CMIP6 Citation Service - its value, your usage and experiences of it as well as your ideas for its further development and sustainable funding or anything else you want to share. </span><br />
