ABSTRACT The mesospheric temperature inversion over Bahir Dar is studied by using SABER satellite data in the year 2012. In this investigation a statistical analysis of the characteristics of mesospheric inversion layers is made. The inversion layer is detected most frequently in the altitude range of 78-80km as lower peak altitude with temperature of 190K. The most frequently upper peak altitude inversion is seen at altitude of 95km with temperature value 177K. The maximum monthly altitude occurrence of inversion is found in May and from October to January. The minimum monthly altitude occurrence of inversion is found in March and July. The maximum seasonal occurrence of inversion is found in summer equinoxes and winter equinox’s periods. The amplitude of inversion temperature is found to be (10-15)K. Key words. Atmospheric thermal structure, Atomic species, Atmospheric dynamics.
