Abstract
Data are provided for the extraterrestrial radiation of the Sun, also for those quantities which are of interest to the illuminating engineer, namely luminance distribution, zenith luminance, illumination, spectral distribution and luminous efficacy of the overcast sky, clear sky and sunlight. Formulae for luminance and illuminance due to several authors are given and shown graphically. CIE recommendations are included.Keywords
