abstract = "Lower-mesospheric inversion layers (MILs) were studied using the
temperature profiles observed by TIMED/SABER over Cariri (7.5°S,
36.5°W), 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.",
