Abstract


A Model of Global solar radiation for atmospheric, environmental and human well-being in Minna, North-Central, Nigeria has been carried out. An empirical correlation equation of the Angstrom type was developed to predict the monthly mean daily global solar radiation incident on a horizontal surface in Minna latitude 9.56oN, longitude 6.54oE, North-Central, Nigeria. Data on monthly mean daily sunshine hours and the global solar radiation amongst others covering a period of about twenty years (1990 – 2010) for Minna was collected from Nigerian Meteorological Agency, Abuja, Nigeria. The required correlation was obtained through regression analysis. The empirical correlation equation obtained is; Results obtained were validated using statistical indicators and compared with measured data and previous findings. Thus, the result obtained is expected to increase baseline data required for human and environmental purposes in Minna, Nigeria.
