Format QA/QC reports summarize compliance of uploaded flux-met data files with the required AmeriFlux FP-In format. Links to Format QA/QC reports are included in an automated email sent to the uploader shortly after uploading.
Review Key Report Components
(3) Overall Status | Action
(2) Autocorrected File Status (if attempted)
(1) Uploaded File Status
Autocorrections (if attempted) are included below the Overall Status | Action.
Test Results contain individual Format QA/QC test details for the Autocorrected (if attempted) and Uploaded Files.
(3) Overall Status | Action
Immediately after a flux-met data file is uploaded, it follows one of the paths below to an Overall Status | Action.
PASS | Ready for Data QA/QC.
All Format QA/QC tests passed.
No further action is needed. Uploaded file will be queued for Data QA/QC.
PASS | Review Recommended.
One or more Format QA/QC tests identified potential issues that may affect data quality. Review of Test Results is recommended to confirm that uploaded data is as expected.
No further action is needed if uploaded file is OK. Uploaded file will be queued for Data QA/QC unless a replacement file is uploaded.
PASS | Autocorrections made. Review Recommended.
One or more Format QA/QC tests failed. An attempt to autocorrect the issues was made, and the autocorrected file was uploaded. We strongly recommend review of the autocorrections. Additional potential issues may be described in the autocorrected file’s Test Results.
No further action is needed if the autocorrected file is OK. Autocorrected file will be queued for Data QA/QC unless a replacement file is uploaded.
FAIL | Replacement file required.
One or more Format QA/QC tests failed and could not be autocorrected. In some cases, an autocorrected attempt was made and also failed. Review details in the uploaded file’s Test Results.
A replacement file is required for further data processing.
(2) & (1): Autocorrected and Uploaded File Status
The file status for each autocorrected or uploaded file are described below.
All Format QA/QC tests passed! Awesome.
One or more Format QA/QC tests had a WARNING result. See Test Results for details.
Review is recommended.
One or more Format QA/QC tests had a FAIL result. See Test Results for details.
Action is required.
A summary of the Format QA/QC results is found in the Format QA/QC report summary.
Each individual QA/QC Test that does not pass is listed in the table with its corresponding Result(s) and Additional Information. See AmeriFlux Format QA/QC Tests for more details.
Potential issues were encountered. A WARNING result may be an informational message to double check that the data are OK. WARNING results may also be minor issues that can either be autocorrected or will minimally affect data quality.
Review of potential issues is recommended. If left unaddressed, some issues may affect Data QA/QC results.
A blocking issue was detected. Some FAIL results can be autocorrected. Others may require a replacement file.

AmeriFlux BASE QA/QC Processing Overview
AmeriFlux BASE QA/QC processing consists of 3 steps: Format QA/QC, Data QA/QC, and BASE Publish.
The Format QA/QC step assesses compliance of flux-met data files uploaded to AmeriFlux with the required FP-In format. Format QA/QC can be an iterative process, especially if data files are being submitted for the first time.
A list of individual Format QA/QC tests can be found at AmeriFlux Format QA/QC Tests.
The Data QA/QC step assesses the data quality of the entire record of flux-met data uploaded to AmeriFlux that has passed Format QA/QC.
A list of individual Data QA/QC tests can be found at AmeriFlux Data QA/QC Tests.
In the BASE Publish step, the AmeriFlux Data team formats the data in the FP Standard format, combines QA/QC’ed flux-met data with BADM** data, provides a DOI for the data, and makes the resulting BASE-BADM data product available to the AmeriFlux community:
- Download Data
- Data Change Log
- Measurement Height
- Site Search for available data by Variable and Years using the Advanced Filters
** BADM = Biological, Ancillary, Disturbance, and Metadata
