Abstract

The project will study the non-linear interaction between planetary waves and lunar tides in the ionosphere over the Brazilian low latitude region. Simultaneous observed data acquired from ionosonde stations at São José dos Campos (23.21 S, 45.97 W; Dip latitude 20.9 S), Jataí (17.93S, 51.72W; dip latitude 12.8 S) and Araguatins (5.65 S, 48.07 W; Dip latitude 4.17 S) will be used for the analysis. The planetary wave and lunar tides signatures will be traced to study how the non-linear interaction facilitates the coupling of neutral atmosphere and ionosphere. It is expected that at the end of this research, the relation between both waves and their coupling processes will be clearly established. (AU)
