Abstract

Study of Atmospheric turbidity is important for purposes of meteorology, ecology, climatology and monitoring of atmospheric pollution. Linke Turbidity factor (LT) is commonly used to model the attenuation of solar radiation in the atmosphere. The probable dependence on the water vapor content of the relationship linking LT to Angstrom’s turbidity coefficient B, is discussed. In this study, a procedure for calculation of Linke turbidity factor is adopted using pyrheliometric measurements by Egyptian Typical Meteorological Year (ETMY) at a Thirteen stations at Egypt, during (from 1969 to 2006). Monthly variations of the LT turbidity factor are found in the three studied months, with a maximum in August and a minimum in July. Detailed studies on the effect of urbanization and industrialization on global solar radiation and the percentage values of radiation loss in the atmosphere, at Egypt, have been performed. The high values of LT (5-6) and B (0.48-0.52) lies between Lat. 28°N-30°N, low values of LT<3.5 and B<0.3 below of Lat. 26°N. 8 cities of the thirteen city used in the study are located in the maximum values of this period is the most civilized cities and concentrated a large part of the population which constitutes a danger to the health of the population and the spread of diseases resulting from atmospheric turbidity.
