3. Data Citations Impact: Determine impact of the ORNL DAAC on Science
Metric: Use citation metrics to indicate how many DAAC data sets have been used in peer-reviewed papers, dissertations, or policy reports
Access: Allow users to find data through the data citations

4. Elements of a data product citation
Authors
Year of publication
Data product title
Examples:
Turner, D.P., W.D. Ritts, and M. Gregory BigFoot NPP Surfaces for North and South American Sites, Data set. Available on-line [ from Oak Ridge National Laboratory Distributed Active Archive Center, Oak Ridge, Tennessee, U.S.A. doi: /ORNLDAAC/750.
Strahler, A.H., C.L.B. Schaaf, and E. Tsvetsinskaya ISLSCP II AVHRR Albedo and BRDF, In Hall, F.G., G. Collatz, B. Meeson, S. Los, E. Brown de Colstoun, and D. Landis (eds.).

Data center and URL
Digital Object Identifiers (after 2008)
Date accessed / version number
IP/copyright:
Institutions and/or funding agencies often have a policy for this
Address any embargos on data due to patents, politics etc.
Intended future uses/users
- Helps determine good data archive to use
By thinking about this at planning stages, can prepare data better for future use/users
Citation
How should dataset be cited
How authors should be credited
Consult policies and options with data archive you will be using
Persistent citation = will not change over time. Consider DOIs 4

5. Data Citations : Impact

6. Data Citations : Metrics

7. Data Citations : Metrics
Highly-cited data (Rivdis, soil texture, LAI, NPP, GFED)
BOREAS
Site-averaged AMS and flux data from FIFE
NPP grasslands
NPP and IGBP-DIS

8. Data Citations : Access

9. Data Citations : Policy

10. Data Citations : Next Steps
ORCID ID can help understand data and author relationships
Data set 1
Author 4
Data set 2
Author 2
Author 1
Author 3

11. Data Citations : Author ID is useful But…..
Community adoption
Incomplete metadata
Permissions to access ORCID ID metadata
Too many ID options (ResearchGate, ORCID..)
Citation databases need to evolve
Publisher adoption
