Eddy correlation flux measurement systems (ECOR) are used by ARM to provide surface turbulence flux measurements. ARM has significantly enhanced its ECOR systems and made them available at all of its observatories and mobile facilities. The Quality-Controlled Eddy Correlation Flux (QCECOR) value-added product (VAP) improves the ECOR data by applying the following quality control (QC) procedures:
- Eddy correlation corrections
- Determination of the quality-controlled energy fluxes from the corrected ECOR fluxes
- Stringent QC checks.
