Developing the Proof of Concept for the SERI QC Flag Translation

Stephen Wilcox, Thomas Stoffel, Aron Habte, Aron Habte (NREL Technical Monitor)

Research output: NRELSubcontract Report


SERI QC is a robust solar data quality assessment software tool that has been in continuous use for more than three decades. This report, the second of six in the Data Quality and Uncertainty Integration project, develops the proof of concept, including programming in C and a collection of spreadsheet tools, for estimating the operational uncertainty from three-component solar irradiance measurements using information available from SERI QC. The report establishes a field reference for determining the operational uncertainty for each irradiance component based on the SERI QC coupling. Results demonstrate that the operational uncertainty estimates based on global irradiance best represent the collective results for all sky conditions.
