abstract

  • AbstractCoefficients are determined for regressions of insolation upon sunshine using data from six West African stations. The analysis, using total, station and monthly data groupings, indicates high correlation (r = 0.86 to 0.99) for monthly groupings. A pronounced annual cycle and range in the coefficients (a = −0.12 to 0.26, b = 0.50 to 0.99), are explained in terms of variations in cloud cover and atmospheric turbidity. A turbidity index ‘t,’ has values similar to those obtained in East Africa.
