Flux/Met Data Processing Overview
Flux/Met data submitted to AmeriFlux are processed using the following pipeline to generate BASE and FLUXNET Data Products:
FP = Flux Processing and refers to the standard variable names, units, and file formats used in AmeriFlux flux/met data products.
The Format QA/QC step assesses compliance of flux-met data files uploaded to AmeriFlux with the required FP-In format. Format QA/QC is fully automated, and results are sent the same day. Format QA/QC can be an iterative process, especially if data files are being submitted for the first time.
Find more details at Format QA/QC and Format QA/QC Tests.
The Data QA/QC step assesses the data quality of a site’s entire record of flux/met data uploaded to AmeriFlux that has passed Format QA/QC. Data QA/QC can be an iterative process, especially for the first data submissions.
Find more details at Data QA/QC.
In the BASE Publish step, AMP formats the submitted data in the FP Standard format, combines quality-checked flux-met data with BADM*, provides or updates the BASE-BADM DOI, and makes the resulting BASE-BADM data product available to the AmeriFlux community. Additional resources are available for site teams and other data users to use the published BASE-BADM product.

* BADM = Biological, Ancillary, Disturbance, and Metadata
AMP is currently building the AmeriFlux implementation of ONEFlux processing codes to generate future versions of the global FLUXNET data product for AmeriFlux sites. The FLUXNET product contains footprint-aggregated data that have been gap-filled and partitioned, and includes uncertainty analysis.
The FLUXNET data product is available as a beta version. Published FLUXNET data products are expected to be available in fall 2021.
