What is Characterization of Sky Conditions by the Use of Solar Radiation Data about?
A method is proposed to characterize the sky and cloud conditions (SCC) by using ground based global/diffuse irradiance data. The term SCC is defined for the purpose of this paper as the bulk effect of clouds, and other atmospheric constituents on the values of the diffuse fraction of solar radiation (D/G), the ratio between the global to extra terrestrial radiation (Kr) and the transmissivity T, measured at the earth's surface. However, there is a difficulty in using the measured values of K, and D/G for describing the SCC since these values depend on the solar zenith angle and not only on meteorological factors. This difficulty is overcome by the use of a simple semi-empirical procedure by which one can eliminate the seasonal and latitudinal variations (due to variations in the solar zenith angle) in D/G and KT, or similar relations, leaving only variations due to SCC. The procedure is based on a paper by Zangvil and Aviv on the effect of latitude and season on the relation between the diffuse fraction of solar radiation and the ratio of global to extraterrestrial radiation, Solar Energy 39, 321-327 (1987) where a numerical simulation of the ,seasonal and latitudinal (zenith angl
