Data Policy

AmeriFlux Data Use Policy

The AmeriFlux Network data offered on this website are contributed by individual AmeriFlux scientists, who share their data openly with the global community.

The AmeriFlux policy is that all data should be properly acknowledged, and that data contributors should have the opportunity to make an intellectual contribution to the papers that use their data and, as a result, have the opportunity to be a co-author.

When you use AmeriFlux data

  • When you download the data, use the Data-Download form to describe how you plan to use the data and if you plan to use in publications. This statement is sent to the data contributor(s), and then posted to the AmeriFlux Data Download Log.
  • When you start in-depth analysis that may result in a publication, contact the data contributors directly, so that they have the opportunity to contribute substantively and become a co-author.

Acknowledge AmeriFlux data in publications—

  • Cite the relevant DOI and/or recommended paper(s). Each site’s DOI is listed on its Site General Info page, DOI tab. (See Sites Search.)
  • Acknowledge funding for site support. If the data download did not provide the preferred acknowledgment language, ask the site principal investigator.
  • List each site using its AmeriFlux Site ID, either in text or in supplementary material. For reproducibility, we recommend specifying the data-years used.

Inform all data providers when publications are about to be published.

Acknowledge the AmeriFlux data resource: “Funding for AmeriFlux data resources was provided by the U.S. Department of Energy’s Office of Science.”

Acknowledge AmeriFlux data in presentations—

  • Use the AmeriFlux logo and/or the AmeriFlux web link (
  • List AmeriFlux sites using their SiteIDs and/or site name

(revised) AmeriFlux Data Contributor Policy

When you contribute data to the AmeriFlux Network, you agree:

That these data will be made available to the global AmeriFlux user community under the AmeriFlux Data Use Policy (above), unless a period of embargo is approved (see AmeriFlux Data Embargo Policy).

That these data will be made available to the FLUXNET community under the FLUXNET Data Use Policy.

To maintain your site metadata (using relevant BADM).

To tend your site instrumentation to assure quality data.

This AmeriFlux data-sharing and data-archiving policy complies with the U.S. DOE Office of Science’s Statement on Digital Management:

Sharing and preserving data are central to protecting the integrity of science by facilitating validation of results and to advancing science by broadening the value of research data to disciplines other than the originating one and to society at large. To the greatest extent and with the fewest constraints possible, and consistent with the requirements and other principles of this Statement, data sharing should make digital research data available to and useful for the scientific community, industry, and the public.
