American Geophysical Union Publications Policy AGU affirmed in its 2012 position statement that: “Earth and space science data should be widely accessible in multiple formats and long‐term preservation of data is an integral responsibility of scientists and sponsoring institutions.” 2 Data Citation and You: The new AGU guidelines for data citation, March. 2014, Ruth Duerr

American Geophysical Union Publications Policy "all data necessary to understand, evaluate, replicate, and build upon the reported research must be made available and accessible whenever possible.” The policy requires: That data availability be listed in the Acknowledgments section Data policy compliance be acknowledged during manuscript submission If data are not available (such as for proprietary or security reasons), a statement to this effect explaining the details for requesting a data policy waiver is included in the Acknowledgment section of the manuscript AND in the Cover Letter. Published data sets should be cited according toESIP Commons guidelines.” 3 Data Citation and You: The new AGU guidelines for data citation, March. 2014, Ruth Duerr

What counts as data? “For the purposes of this policy, data include, but are not limited to, the following: Data used to generate, or be displayed in, figures, graphs, plots, videos, animations, or tables in a paper. New protocols or methods used to generate the data in a paper. New code/computer software used to generate results or analyses reported in the paper. Derived data products reported or described in a paper. 4 Data Citation and You: The new AGU guidelines for data citation, March. 2014, Ruth Duerr

Where should my data be? AGU encourages authors to identify and archive their data in approved data centers (http://publications.agu.org/files/2014/01/Data- Repositories.pdf) Many AGU journals allow supplements Otherwise, authors are expected to "curate the data for at least 5 years after publication and provide a transparent process to make the data available to anyone upon request.” 5 Data Citation and You: The new AGU guidelines for data citation, March. 2014, Ruth Duerr

Mandatory Content: Title This is the formal title of the data set - not of the project or a related publication. Doe, J. and R. Roe. 2001. The FOO Data Set. The FOO Data Center.http://dx.doi.org/10.xxxx/notfoo.547983. Accessed 1 May 2011. 12 Data Citation and You: The new AGU guidelines for data citation, March. 2014, Ruth Duerr

Mandatory Content: Archive and/or Distributor This is the organization that maintains and manages the release or distribution of the data set. There is often an implied responsibility for stewardship of the data set. "The entity that holds, archives, publishes, prints, distributes, releases, issues, or produces the resource. This property will be used to formulate the citation, so consider the prominence of the role."- DataCite This may be an appropriate place to recognize a major sponsor of the data. Doe, J. and R. Roe. 2001. The FOO Data Set. The FOO Funding Agency Data Center. http://dx.doi.org/10.xxxx/notfoo.547983. Accessed 1 May 2011. 13 Data Citation and You: The new AGU guidelines for data citation, March. 2014, Ruth Duerr

Mandatory Content: Versions Careful versioning and documentation of version changes are central to enabling accurate citation. Data stewards need to track and clearly indicate precise versions as part of the citation for any version greater than 1. It may be appropriate to track major and minor versions. Doe, J. and R. Roe. 2001. The FOO Data Set. Version 2.3. The FOO Data Center.http://dx.doi.org/10.xxxx/notfoo.547983. Accessed 1 May 2011. 14 Data Citation and You: The new AGU guidelines for data citation, March. 2014, Ruth Duerr

Mandatory Content: Locator, Identifier, or Distribution Medium Background If there is one fixed medium, indicate it. For example, CD-ROM, DVD. More typically, data are available over the internet or through multiple digital media options. Then it is necessary to include a persistent reference to the location of the data. Any reasonably persistent location service such as DOIs, ARKs, Handles, PURLs etc. is acceptable. Scientific publishers, however, are most familiar with the DOI. Furthermore, Thomson Reuters, who manages the Web of Science, now indexes data sets. Data sets that are cited by articles in the Web of Science also show up in Web of Science, so there is an incentive for authors to cite data sets. 15 Data Citation and You: The new AGU guidelines for data citation, March. 2014, Ruth Duerr

Mandatory Content: Locator, Identifier, or Distribution Medium Persistent identifiers should point to a data landing page that describes and provides access to the data. Other locators and identifiers may be more appropriate for locating individual records or files. Best practice is that the suffix of the identifier does not include a reference to the archive in case the data are moved from the original location where the persistent identifier was assigned initially. Doe, J. and R. Roe. 2001. The FOO Data Set. The FOO Data Center. CD-ROM. Doe, J. and R. Roe. 2001. The FOO Data Set. Version 2.3. The FOO Data Center. http://dx.doi.org/10.xxxx/notfoo.547983. Accessed 1 May 2011. 16 Data Citation and You: The new AGU guidelines for data citation, March. 2014, Ruth Duerr

Mandatory Content: Access Date and Time Because data can be dynamic and changeable in ways that are not always reflected in release dates and versions, it is important to indicate when on-line data were accessed. Depending on how frequently the data change, it may be necessary to include time as well as date of access. Doe, J. and R. Roe. 2001. The FOO Data Set. Version 2.3. The FOO Data Center.http://dx.doi.org/10.xxxx/notfoo.547983. Accessed 1 May 2011. 17 Data Citation and You: The new AGU guidelines for data citation, March. 2014, Ruth Duerr

As Needed Content: Subset Used It is necessary to enable "micro-citation" or the ability to refer to the specific data used--the exact files, granules, records, etc. Equivalent to quoting a certain passage in a book, where one then references a specific page number in the citation. Alternatively, one might make reference to the "structural index" of a canonical text (e.g. book, chapter, and verse in the King James Bible). 18 Data Citation and You: The new AGU guidelines for data citation, March. 2014, Ruth Duerr

As Needed Content: Subset Used Use the structural form of a data set to cite a specific subset. With Earth science data, subsets can often be identified by referring to a temporal and spatial range. Doe, J. and R. Roe. 2001, updated daily. The FOO Gridded Time Series Data Set. Version 3.2. Oct. 2007- Sep. 2008, 84°N, 75°W; 44°N, 10°W. The FOO Data Center.http://dx.doi.org/10.xxxx/notfoo.547983. Accessed 1 May 2011. Sometimes, the data may be packaged in different sub- collections or representations which can be referenced. Doe, J. and R. Roe. 2001. The FOO Data Set. Version 2.0 shapefiles.
