European intercomparison of ultraviolet spectroradiometers

摘要: Abstract Accurate spectral measurements of solar ultraviolet radiation are essential to an understanding the photochemical and biological effects ozone depletion. The analysis spatial temporal variations in fluxes will depend on collation spectra from many independent laboratories. However, results diverse instruments operated isolation may not be consistent with each other. To investigate compatibility different designs spectroradiometer, a blind trial six distinct instrument types was carried out at suburban site Greece. Comparisons were performed daylight, tungsten lamps indoors. Excellent agreement obtained relative response instruments, but their absolute lamp calibrations varied, did generally agree daylight experiments. Simultaneous scans by all revealed discrepancies attributable stray light, bandwidth, cosine response, which would otherwise...
