Abstract
The spectral composition of direct solar radiation and its long-term t rends for the period 1963-1990 over Athens have been studied. Measurem ents were made with the use of QRT, OG1, RG2 and RG8 Schott glass filt ers, allowing the division of the solar spectrum into 4 bands. The per centage of direct normal solar irradiance was found to increase in the wavelength regions under 630 nm and to decrease in the regions with l onger wavelengths.
