## Abstract Measurements of the spectral distribution of global and diffuse solar radiation made in both wide and narrow wavebands are reported. Relationships between the ratio of diffuse to global irradiance, Ξ±, in both the visible and total solar wavebands, and atmospheric turbidity and zenith an
In the present analysis broad-band turbidity parameters, which depend upon the attenuation over the entire solar spectrum and which can be determined from unfiltered pyrheliometric measurements of direct beam solar irradiance, are presented. Unsworth-Monteith attenuation coefficient Tm, Linke facto
