AmeriFlux Data

The AmeriFlux data archive at the Carbon Dioxide Information Analysis Center (CDIAC) offers two types of AmeriFlux data. Preliminary data are contributed by AmeriFlux principal investigators (PIs). The file formats and contents are unchanged from their original submission state. Any descriptive files provided are those furnished by the site PIs. The values provided in these preliminary files have been scrutinized by the PIs but are subject to change . Preliminary AmeriFlux data are kindly contributed to CDIAC and made available in order to make AmeriFlux measurement data available as quickly as possible. Users are REQUIRED to communicate with the contributing PIs BEFORE performing data analyses and are reminded that data used for publication are subject to AmeriFlux FAIR USE rules.

Preliminary AmeriFlux data sent to CDIAC are checked, processed into a consistent data format, and documented by CDIAC before release as a final data set. All data issues investigated by CDIAC are resolved with the contributing PIs and no values are changed without the approval of the contributing AmeriFlux PIs. Again, users are REQUIRED to interact with the contributing PIs before publishing any results based on final AmeriFlux data and reminded that data used for publication are subject to AmeriFlux FAIR USE rules.
