Atmospheric effects on the ultraviolet erythemal and total shortwave solar radiation in Valladolid, Spain

Abstract

Changes in erythemal and total shortwave due to variations in geometrical and atmospheric factors have been analyzed and quantified. The ozone, aerosol and water vapour effect on solar radiation has been obtained using radiation measurements at different fixed solar zenith angles. The results have showed a negligible effect of ozone on total shortwave radiation, and a stronger attenuation provided by aerosols in the erythemal case. © Sociedad Española de Óptica.
