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 S{\~a}o
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.",
