| Abstract | ||||
| The ultraviolet component of solar radiation was measured in Egypt for the last years by the Meteorological Authority of Egypt, in Cairo and Aswan stations. Cairo represents the typical weather conditions for Lower Egypt and Aswan represents the typical weather conditions for Upper Egypt. Measured data of global and ultraviolet solar radiation in Cairo and Aswan for the period (1990-1992) have been processed, arranged, discussed and used to investigate an empirical relationship with correlation coefficient 96%. This empirical relationship was used in calculating the ultraviolet component of solar radiation in Cairo, Aswan and other selected locations(Matrough, Al-Arish, Bahtim and Al-Kharga) during other two years (1993 and 1994). The calculated values of ultraviolet radiation were compared with the measured data at both Cairo and Aswan sites and were in a good agreement. This encourages the use of the empirical formula in calculating the components of ultraviolet solar radiation at any other location over Egypt . | ||||
