abstract = "The atmospheric lunar tide is excited by gravitational action in
the lower atmosphere and by the movement of the oceans and Earths
surface. Due to the fact that the source of the lunar tide does
not change, the determination of this oscillation in the
ionosphere is an excellent tool for understanding the coupling
mechanism between the neutral and ionized atmospheres. The lunar
tide has been studied in the mesosphere-thermosphere-ionosphere in
different longitudinal sectors and using different observational
techniques and simulations. However, there are some aspects of
lunar tide that still need explanation, for example, the temporal
variability of this oscillation. So, in this work, the diurnal and
semidiurnal lunar tides are investigated in the ionosphere using
ionosonde data over Brazil. The ionosonde measurements were
collected at Cachoeira Paulista (22.7\◦ S; 45.0\◦ W)
and Sao Luis (2.6\◦ S; 44\◦ W) from 2001 to 2009
with a temporal resolution of 15 minutes. Using these data, it was
possible to extract the characteristics of the lunar tide. Salient
features of this oscillation are presented and discussed in this
work. For instance, the semidiurnal lunar tide is dominant
comparing to the diurnal tide and had amplitude of 0.6 MHz in foF2
and 7 km in hmF2.",
