“…Among these models, Kenisarin and Tkachenkova (1990) and Dincer et al (1995) presented the most simple ones. Experimental data for the first model were measured in Ozbekistan and Tadjikistan, while those for the latter model were obtained from the measurements in Gebze, located in the northwestern part of Turkey.…”

“…They proposed relations using Fourier series for estimating global solar radiation depending on the ambient air temperature. Dincer et al (1995) found that there is a strong relation between the ambient temperature, T and the solar radiation parameters, I and developed the relations in the form of a fifth-order polynomial correlation given by…”

“…Numerous researchers have conducted experiments to develop correlations for various locations in Turkey, e.g. Gebze (Dincer et al, 1995;Tiris and Tiris, 1997;Sen and Tan, 2001), Elazig (Togrul and Onat, 1999), Trabzon (Kaygusuz, 1999), Antalya (Ertekin and Yaldiz, 1999;Ertekin and Yaldiz, 2000), Izmir (Ulgen and Hepbasli, 2002) and also for Turkey's general values (Tasdemiroglu and Sever, 1991a;Tasdemiroglu and Sever, 1991b).…”

SUMMARYIn this study, the solar radiation parameters (global and diffuse solar radiation) are correlated with respect to ambient temperatures in the fifth-order polynomial form for Izmir in Turkey. Experimental data were measured in the Solar-Meteorological Station of Solar Energy Institute in Ege University over a 5-yr period, 1994-1998. The ratios of the total daily diffuse to global radiation intensities for each month range from 0.38 to 0.45 averaged for the same period, with an average value of 0.41. It can be concluded that the present models predict the solar radiation parameters reasonably well with the correlation coefficients over 0.95 for the projections.

“…Therefore, predictions about solar radiations at specific locations are still useful for many practical purposes. Several studies have been presented [11,12] for the prediction of solar radiation in various cities and locations in Turkey. Solar radiation intercepted at the earth's surface is of paramount importance for various applications, such as in the infrastructure and construction industry, estimation of crop productivity, environmental and agrometeorological research, atmospheric physics and the practical utilization of renewable energy resources [13].…”
