Abstract :
This paper presents the results of a study of surface refractivity N for three locations in Lebanon. Monthly, diurnal and hourly variations for N are investigated. The results indicate the presence of two distinct climatic regions separated by a range of mountains. The coastal region has higher values of N and its variation. It is a super-refractive region. The Bekaa area has more of a temperate continental climate
