Calibration Traceability
Apogee Instruments SP series pyranometers are calibrated through side-by-side comparison to the mean of four
Apogee model SP-110 transfer standard pyranometers (shortwave radiation reference) under high intensity
discharge metal halide lamps. The transfer standard pyranometers are calibrated through side-by-side comparison
to the mean of at least two ISO-classified reference pyranometers under sunlight (clear sky conditions) in Logan,
Utah. Each of four ISO-classified reference pyranometers are recalibrated on an alternating year schedule (two
instruments each year) at the National Renewable Energy Laboratory (NREL) in Golden, Colorado. NREL reference
standards are calibrated to the World Radiometric Reference (WRR) in Davos, Switzerland.
