Özet:

 

The aim of this paper is to evaluate the global solar radiation of some representative cities of Cameroon using the linear Angstrom and non-linear polynomial relations. The choice of these cities which include: Bamenda in the North West region, Douala in the littoral region, Yaounde in the centre region, Ngaoundere in the Adamawa region, and Bertoua in the eastern region; is determined mostly by the availability of data. The Angstrom correlation coefficients for the linear, quadratic and cubic polynomial models would be calculated using the least square method for the different regions. The input data for the analyses are the measured global solar radiation and mean number of monthly sun shine hours. The data for the analyses is obtained partly from the archives of National Aeronautics and Space Administration (NASA) and partly from the archives of the Cameroon Department of Meteorology, Douala. The data used covers a period of 23 years from 1983 to 2005. We demonstrate the validity of the developed models by comparing the evaluated values of global solar radiation with the measured ones. Hence the regression equations can be used to confidently predict the global solar radiation of the representative regions in the absence of experimental data.
