The Norwegian UV-monitoring network, implemented in 1995, has provided up to 16 years measurement data from currently 9 stations located from 59° N to 79°N. The intention is to provide measurements of high scientific quality for the spatial and temporal variability of UV and for information to the public about solar exposure. The stations are equipped with GUV multiband filter radiometers from Biospherical Instruments Inc. The irradiance scale is maintained with a travelling reference instrument, traceable to the QASUME European reference spectroradiometer. Blind test intercomparisons of UV index measurements at the local sites have shown close agreement with the QASUME unit. Changes in yearly UV doses for two of the coastal stations have shown an upward trend for the period 1999-2011. Changes in cloudiness had the largest influence on UV doses in this period.
