摘要: With the transportable reference spectroradiometer QASUME (Quality Assurance of Spectral Ultraviolet Measurements in Europe) routine quality assurance spectrally resolved solar ultraviolet irradiance measurements were successfully performed at 25 UV monitoring sites Europe. The absolute scale carried by is traceable to primary standard Physikalisch-Technische Bundesanstalt (PTB), Braunschweig, Germany, and has proved represent average use independent European laboratories; it can thus be taken as a reference. Out 27 instruments 13 showed deviations relative less than 4% UVB (15 UVA) for zenith angles below 75 ◦ . results so far have shown unique possibilities offered this providing on-site measurements.
