Scientific paper

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 eta (as defined by Krassovsky, 1972). While some of the observed OH intensity-temperature fluctuations were correlated and had absolute values of eta (AVE) less than 1, two correlated intensity-temperature waves with periods of 4 and 2 h were seen with AVE = 3.1 + or - 1.1 and 1.6 + or - 0.5, respectively; the respective phase angles between the intensity and temperature components were 5 + or - 23 and 40 + or - 20 deg. These results are consistent with the theoretical model of Walterscheid et al. (1987) for the passage of AGWs through an OH emission layer. Agreement is closest for the 4-h-period waves when the layer is peaked at 87 km and the O scale height is -2.0 km (83 km and -4.0 km for the 2-h-period waves).
