AB Ultraviolet (UV) radiation is the most energetic among all extraterrestrial sources that reachthe Earth, being able to cause multiple effects on live beings inhabiting it. There are numerousfactors controlling the amount of radiation reaching, as well as the way it hits the Earth’s surface.In this study, the effect of two of the main UV radiation modulators, clouds and aerosols, whichcan absorb or scatter radiation; is analyzed.There are simulated data for clear sky conditions at our disposal, obtained by LibRadtran radiativetransference model. They are validated, in the first place, proving that they are an accurateapproximation to experimental data measured on cloud-free sky days. Once their usefulness iscertified, cloud and aerosol enhancing or attenuating effect over spectral UV radiation is quantifiedin the solar UV wavelength range. For this purpose, a cloud characteristic parameter, CMF (CloudModification Factor), is calculated as a function of sky cloudiness and solar zenith angle (SZA),while a similar procedure is followed with an aerosol parameter, AMF (Aerosol Modification Factor),calculated as a function of aerosol optical depth (AOD) and SZA.
