| Zusammenfassung |
A bi-lateral intercomparison of erythemal broadband radiometers was performed
between seven UV calibration facilities. The calibrations provided by the
instruments owners were compared relative to the characterisation and
calibration performed at PMOD/WRC in Davos, Switzerland. The calibration
consisted in the determination of the spectral and angular response of the
radiometer, followed by an absolute calibration performed outdoors relative
to a spectroradiometer which provided the absolute reference.
The characterization of the detectors in the respective laboratories are in
good agreement: The determinations of the angular responses have deviations
below ±4% and the spectral responses agree within ±20%. A "blind"
intercomparison of the erythemally weighted irradiances derived by the
respective institutes and PMOD/WRC showed consistent measurements to within
±2% for the majority of institutes. One institute showed slightly
larger deviation of 10%. The differences found between the different
instrument calibrations are all within the combined uncertainty of the
calibration. |
