Simultaneous observations of four nightglow emissions are analyzed. Graphs of diurnal variations of the emission intensities and cross correlations of the emission for various time shifts are provided. The analysis reveals that the O2(1Sigma)(0-1) band correlates with the OI-green line, O2(0-1) correlates with NaD lines with a time lag of 0.5 h, and O2(0-1) and OH(6-2) bands correspond after a phase lag of 1 h. Good correlations between OH(6-2) and NaD emissions, and NaD and OI-557.7 nm lines after a 0.5 h time lag are observed. The relation of phase lags and the altitude of emission layers to the vertical structure and atmospheric oscillations are examined.
