18 radiative transfer models in use for calculation of UV index are compared with respect to their results for more than 100 cloud free atmospheres, which describe present, possible future, and extreme conditions. The comparison includes 6 multiple scattering spectral models, 8 fast spectral models and 4 empirical models. Averages of the results of the 6 participating multiple scattering spectral models are taken as a basis for assessment. The agreement among the multiple scattering models is within ± 0.5 UV index values for more than 80 % of chosen atmospheric parameters. The fast spectral models have very different agreement, between ± 1 and up to 12 UV index values. The results of the empirical models agree reasonably well with the reference models, but only for the atmospheres for which they are adjusted.
The data to describe the atmospheric conditions, which are used for the comparison, together with the individual results of all participated models and model descriptions, are available on Internet: http:/www.meteo.physik.uni-muenchen.de/strahlung/cost/
