International Intercomparison of Solar UVR Spectral Measurement Systems in Melbourne in 2013

摘要: Monitoring ambient solar UVR levels provides information on how much there is in both real time and historically. Quality assurance of measurements critical to ensuring accuracy stability this can be achieved by regular intercomparisons spectral measurement systems with those other organizations. In October November 2013 a spectroradiometer from Public Health England (PHE) was brought Melbourne for campaign new Bentham spectrometer Australian Radiation Protection Nuclear Safety Agency (ARPANSA) one at the Bureau Meteorology (BOM), supported New Zealand's National Institute Water Atmosphere (NIWA). Given all three spectroradiometers have calibrations that are traceable various national standards, intercomparison chance determine uncertainties traceability support UV networks Australia, Zealand UK. Index were compared ratios determined clear sky conditions when scans each instrument within 2 min other. While wavelengths below 305 nm showed substantial differences between PHE unit two systems, overall results encouraging, mean measured BOM/NIWA ARPANSA <0.1% 7.5%, respectively.
