  • Quality assurance of spectral ultraviolet measurements in Europe through the development of a transportable unit (QUASUME), report of site visits, round 2004


QASUME is a European Commission funded project that aims to develop and test a transportable unit for providing quality assurance to UV spectroradiometric measurements conducted in Europe. The underpinning idea is to perform the comparisons at the home sites of the instruments, thus avoiding the risk of transporting instruments to participate in intercomparison campaigns. Spectral measurements obtained at each of the stations will be compared, following detailed and objective comparison protocols, against collocated measurements performed by a thoroughly tested and validated travelling unit.
The transportable unit comprises a spectroradiometer (B5503), its calibrator with a set of calibration lamps traceable to the primary standard of a Standards Laboratory, and devices for the determination of the slit function and the angular response of the local spectroradiometer. The unit is transported by road to each UV monitoring station for a measurement period of about five days to check the absolute calibration and the overall performance of the local spectroradiometer. Thus it will be possible to certify the quality of the measurements obtained by each instrument, as well as the status of each station�s calibration standards.
