             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.",
