OH nightglow emissions from the (6, 2) band were observed during February 12--14, 1986, at Sondre Stromfjord, Greenland. The data were analyzed using time series analysis techniques to determine &eegr;=(ΔI/I)/(ΔT/T), where ΔI and ΔT represent correlated fluctuations from the mean OH intensity (I) and temperature (T) in various frequency bands. For correlated fluctuations due to measurement error, ‖&eegr;‖1.5. The 4-hour (2-hour) period wave had an ‖&eegr;‖ equal to 3.1¿1.1(1.6¿0.5) and a phase angle, between the intensity and temperature components, of 5¿+23¿ (40¿+20¿C). These results are consistent with a recent theoretical model for the passage of AGWs through an OH emission layer. Agreement is closest for the 4-hour (2-hour) period wave when the layer is peaked at 87 km (83 km) and the O scale height is -2.0 (-4.0km). ¿American Geophysical Union 1987
