Özet
A total of 96 empirical models in linear, quadratic, cubic, logarithmic, exponential and hybrid forms using geographical and meteorological data were compared to estimate monthly average daily global solar radiation on a horizontal surface for 159 weather stations in Turkey. As a function of sunshine duration only, Jin et al. (2005) model provided most robust performance based on the error statistics of the coefficient of determination (R2), the mean percentage error (MPE), the mean bias error (MBE), and the root mean square error (RMSE). As a function of mean air temperature, precipitation, and sunshine duration, Chen et al. (2006) model gave best results. A comparison of observed and predicted monthly average daily global solar radiation for 35 sites typical of the major climate zones of Turkey had high R2 values. Spatial variability in mean annual global solar radiation observed was mapped using universal (co-)kriging with the spherical semi-variogram model. Crossvalidation statistics indicated that universal (co-)kriging was sufficiently reliable in prediction of spatial variability in global solar radiation across the country, particularly, in areas with a lack of incident solar radiation data.
