abstract = "Medium-scale gravity waves have been observed in the OH airglow
images at Sao Joao do Cariri (36.5ºW; 7.4ºS). During two years of
observation by about 100 gravity waves have been observed and
their horizontal parameters have been estimated. Most of the
gravity waves propagates to the Northeastward direction. These
waves range from few minutes to almost two hours of observed
period. Regarding to the observed phase speed, the gravity waves
range from 50 m/s to 200 m/s. It corresponds to wavelength, which
extends from 50 km to 400 km. In addition, the vertical
characteristics of these waves have been investigated using
TIMED/SABER satellite data, ever coincident sounding of the
satellite crossed the field of view of the imager. Only few
coincident measurements were possible. In this paper, we have
studied two of these events in details. According to the theory of
gravity waves, these observed waves can be either primary or
secondary gravity waves. Studying the vertical and horizontal
characteristics of these waves, we will be able to know the
frequency of occurrence of secondary gravity waves in the
equatorial region.",
