Resumen:
The solar radiation at Earth surface is measured usually with instruments of narrow or large wavelengths bands.
However, for different applications like the determination of irradiances related to biological actions and substance and
material degradations, it is needed to know the spectrum at all wavelengths with reasonable resolution. In CEILAP

measurements of solar UV irradiance in clear sky days in the UV range (300 400 nm) range with a spectroradiometer
Monospec 27 of National University of Rosario. The data represented in a 3D diagram show the variations in the solar
spectrum along the day as function of the solar zenith angle. From the comparison with the results obtained employing
the TUV program developed by MadronichlNCAR that solves the radiative transfer equation, it is possible to determine
the influence of the ozone and aerosol atmospheric components on this irradiance. The spectra were calibrated against
the absolute measurements made with an instrument GUV 541 at wavelengths of 305, 320, 340 and 380 nm, which is400 nm) range with a spectroradiometer
