PDFAbstract: The usefulness of empirical formulae for parameterization of unavailable solar radiation in Nigeria cannot be over emphasized owing to the availability of the solar radiation as well as the need for its conversion to other usable solar systems. In this paper we have obtained empirical formulae for parameterization of unavailable solar radiation for fourteen meteorological stations in Nigeria: Bauchi, Bida, Enugu, Gusau, Ikom, Jos, Kano, Maiduguri, Minna, Nguru, Potiskum, Yelwa, Yola and Zaria. Most of the stations studied showed high correlation for seasonal fits ( 0.97). For yearly fits, relative humidity appears to be an important climatological parameter for Enugu, Jos and Potiskum, while this is not a determining factor for Ikom and Nguru.
Keywords: parameterization, relative humidity, best fit, regression
