During much of 2001 and 2002, spectral irradiance measurements of solar ultraviolet radiation (UVR) were made in Melbourne by both the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) and the Bureau of Meteorology (BOM).
The two measurement sites are separated by 12km. Both instruments made measurements on selected days, generally as clear and cloud free as possible. Examination of the two data sets gave 15 days when both instruments collected sufficient data to allow comparison. The spectral measurements made by ARPANSA provide calibrations for the network of radiometric detectors based in the Australian Capital cities.
Comparison with the BOM data gives independent traceability to the measurements of spectral irradiance through two separate spectral irradiance standards (Australia and New Zealand). UV Index results from the two
