Tidal features have been detected in OH Meinel (6,2) and O2atmospheric (0,1) rotational temperatures
obtained at Adelaide, Australia (34.9° S, 138.6° E) and South Pole (90° S). Rotational
temperatures obtained from the OH (6,2) and the O2atm (0,1) bands are in general agreement and exhibit
the same trends. Wavelike modulations and tidal spectral peaks at 6, 8 and 12 hours were simultaneously
observed in the rotational temperatures of the OH (6,2) and the O2atm (0,1) bands. Because the two bands
peak at different altitudes (~87 km and ~95 km, respectively), the amplitudes and phases at the two
altitudes are used to calculate vertical wavelengths, phase speeds, and direction of propagation of the tides.
Seasonal and annual variations in the tidal amplitudes are determined and compared to model outputs. Non-
linear coupling and modulation of the tides by planetary waves is also investigated.
