                         temperature profiles observed by TIMED/SABER over Cariri (7.5S, 
                         36.5W), Brazil, in 2005. A total 175 MILs were identified with 
                         the maximum occurrence in April and October and the minimum in 
                         January and July. The lower MIL is located in a height region from 
                         70 to 90 km, with the peak at around 83  4 km with the 
                         temperature of 205  5 K, and the thickness of 410 km. The results 
                         show large amplitudes of MILs during equinoxes and minimum in 
                         solstices, with a clear semiannual variation. A general feature of 
                         lower MIL in monthly mean profile was observed twice a year, one 
                         from February to May, and the other from August to October with a 
                         downward shift of the top level. These results suggest that 
                         formation and long persistence of MIL is an important factor to 
                         investigate propagation of atmospheric gravity waves in the 
                         mesosphere-lower thermosphere (MLT) region.",
