Abstract: 
Ground-based simultaneous observations of four airglow features are analysed. The diurnal variations of the emission intensities and cross correlations between them for various time shifts are presented. It is found thatO2(1∑)(0-1) band correlates very well with OI-green line with no variation with season. The maximum correlation of O2(0-l) with NaD lines is obtained when a time lag of 0.5 h is considered. A lag of l h improves the covariation between O2(0-1) and OH(6-2) bands. The OH(6-2) band lags l h behind the green line emission, but their mean correlation coefficient keeps below 0.2, being the lowest of all relations studied. Very good correlation is obtained between OH(6-2) and NaD emissions with a time lag of about 0.5 h, and the same lag occurs between NaD and OI-557.7 nm lines. The difference in the altitudes of the emission layers and the phase lags observed between the emissions provide information on the vertical structure and on atmospheric oscillations in the middle atmosphere. © 1985.
