It is a joint recommendation of World Health Organisation (WHO) and World Meteorological Organisation (WMO) to use the UV Index (UVI) for informing the public about possible risks due to overexposure to solar radiation, especially the skin damage. To test the current operational status of measuring and modelling techniques used for UVI information of the public, in this article, cloudless sky UVIs, measured with 5 instruments at 4 locations with different latitude and climate are compared with the results of 13 models, used in UVI forecasting schemes. For the models only location, total ozone and solar zenith angle were provided as input parameters. In many cases the agreement is acceptable, i.e. less than 0.5 UVI. Larger differences may originate from instrumental errors and shortcomings in the models and their input parameters. A possible explanation for the differences between models is the treatment of the unknown input parameters, especially aerosols | [keywords]
