Abstract: 

The dependence of Ultraviolet A and Ultraviolet B on wavelength as well as the fit of the sun height, approximation has been investigated under the location Biskra city of Algeria. The study is based on spectral data acquired with both spectral wavelengths: (280–315 nm) (315–400 nm). Under clear conditions Ultraviolet A and B are the main atmospheric components responsible for direct effects on earth. Measurements of Ultraviolet A and B properties along with simultaneous measurements of global solar irradiances were recorded at an urban site (Biskra, Algeria) to characterize the radiative effect of atmospheric from January to December 2013. This relationship constitutes an alternative tool for estimating Ultraviolet A and B from routine irradiance measurements available from numerous radiometric stations worldwide. The results of the proposed model were compared with the experimental data and there was an excellent correlation between the results obtained. We conclude from this study with a good result between measurement data and prediction which done a perfect approximation with a great convergent.
