    Abstract: The global solar radiation and sunshine hour duration measured over a period of thirteen years (2000 - 2012), were used to establish an Angstrom-type correlation equation (model) for estimating total solar radiation falling on a horizontal surface in Bida (lat. 9.1°N, long. 6.02°E). Six other existing correlations involving global solar radiation a... Show More
