There are many locations where no measured data on diffuse radiation are available in Turkey, so it has to be estimated from empirical correlations. In order to obtain the diffuse radiation for practical application at various locations, seven theoretical models for calculating the monthly-mean, daily, diffuse radiation as a function of atmospheric parameters were applied to measured data in Trabzon. Results of error analyses and monthly-mean, daily, diffuse calculations are given.
