Recommendation:
A space-separated list of documentation DOIs should be used in the CF references attribute in Earth Science data products, both globally and for specific variables.
Recommendation Details:
The CF references attribute is useful for storing information regarding documentation in Earth Science data products. The CF references attribute can exist both globally and at the variable level. The most concise way to reference a document is via its DOI. We suggest that a space-separated list of documentation DOIs should be used in the CF references attribute in Earth Science data products. Use of the URL form of the DOI is strongly recommended. Also, URLs of relevant documents that do not have DOIs can be used in the CF references attribute.
Awaiting ESO Approval
