Abstract: Two different procedures are explored in the present work to estimate the zenith luminance at the International Daylight Measurement Program station in Madrid, when all the data available are used independently of the sky type. On the basis of the results obtained, correlations for the seasonal dependence of the zenith luminance on solar elevation are reported. However, it is observed that polynomials obtained for different ranges of the luminous clearness index, the ratio of global to extraterrestrial illuminance, can predict the zenith luminance with a more reasonable accuracy. The results show that the luminous clearness index is an important parameter for zenith luminance characterization, to be used when global illuminance values on horizontal surfaces are available, but diffuse illuminance is not measured
