A number of years of data on the global irradiation incident on a horizontal surface in Beer Sheva, Israel (lat. = 31°15′N, long. = 34°48′E, elevation ∼ 240 m) have been correlated. It is apparent from these data that this locale possesses a relatively high abundance of sunshine. The average cumulative annual irradiation is 6722MJ/m2 and the average daily irradiation is 18.43 MJ/m2. The percentage frequency of days possessing irradiation rates greater than 20 MJ/m2 is 46 per cent, whereas that possessing less than 10 MJ/m2d is 11.9 per cent. The percentage frequency of cloudy days (KT < 0.34) is low, 7.5 per cent, whereas that for clear days (KT > 0.65) is 29.2 per cent.
