Estimating global solar radiation on horizontal surface from sunshine hours over Port Harcourt, Nigeria

A model for estimating sunshine hours from some meteorological parameters was developed. An eleven year (1997 to 2007) period of relative humidity, maximum and minimum temperatures, rainfall and wind speed measured at Port Harcourt, Nigeria (Latitude 4°56’26.2’’N) was analyzed. The results of the correlations show that the four variable correlations with the highest value of R gives the best result...
