Empirical equations have been developed which correlate the monthly-average daily horizontal global, diffuse and beam radiations with the fraction of maximum possible number of sunshine hours. These correlations are based on measured data between 1988 and 1992 from the TÜBİTAK-MRC station in Gebze, Turkey. The correlation models have been tested by using statistical error tests.
