Abstract
Ultraviolet (UV) radiation is the most energetic among all extraterrestrial sources that reach
the Earth, being able to cause multiple effects on live beings inhabiting it. There are numerous
factors 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, which
can absorb or scatter radiation; is analyzed.
There are simulated data for clear sky conditions at our disposal, obtained by LibRadtran radiative
transference model. They are validated, in the first place, proving that they are an accurate
approximation to experimental data measured on cloud-free sky days. Once their usefulness is
certified, cloud and aerosol enhancing or attenuating effect over spectral UV radiation is quantified
in the solar UV wavelength range. For this purpose, a cloud characteristic parameter, CMF (Cloud
Modification 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.
