Vertical propagation of gravity waves determined from zenith observations of airglow

From our growing data base of OH and O2 airglow intensity and temperature measurements at lower mid-latitudes, gravity wave information has been extracted by time series spectral analysis. According to existing theories, the amplitude and phase relationships between intensities and rotational temper...
