Abstract
An Eppley Normal Incidence Pyrheliometer (NIP) was used to measure the duration of the bright sunshine for Dhahran. These measurements were used to derive a linear correlation between the monthly average daily global solar radiation and the sunshine duration. On an annual basis, the agreement between the predicted and the measured global values is better than 4%. Assessment of the deviations between the measured and the computed global radiation for 11 Saudi Arabian stations are reported. We also found that the Dhahran radiation data fit the theoretical curve of Liu and Jordan, which correlates hourly values and daily totals of the global radiation.
