“…Of the importance is that Reisin and Scheer (2001) found η values of 3.47 ± 0.07 corresponding to the wave periods between 1000 s and 3 h. Our observed values of η (arithmetic mean, 4.4 ± 1 for the year 2010 and 5.7 ± 1.7 for 2011) for OH measurements agree well with this report. In another study based on long-term observations with a spectral airglow temperature imager (SATI) from a mid-latitude station, Lopez-Gonzalez et al (2005) reported a mean value of η of approximately ∼ 8.6 for the OH measurements with a larger variability than our observations show.…”

Abstract. Quasi-monochromatic gravity-wave-induced oscillations, monitored using the mesospheric OH airglow emission over Kolhapur (16.8 • N, 74.2 • E), India, during January to April 2010 and January to December 2011, have been characterized using the Krassovsky method. The nocturnal variability reveals prominent wave signatures with periods ranging from 5.2 to 10.8 h as the dominant nocturnal wave with embedded short-period waves having wave periods of 1.5-4.4 h. The results show that the magnitude of the Krassovsky parameter, viz. |η|, ranged from 2.1 to 10.2 h for principal or long nocturnal waves (5.2-10.8 h observed periods), and from 1.5 to 5.4 h for the short waves (1.5-4.4 h observed periods) during the years of 2010 and 2011, respectively. The phase (i.e., ) values of the Krassovsky parameters exhibited larger variability and varied from −8.1 to −167 • . The deduced mean vertical wavelengths are found to be approximately −60.2 ± 20 and −42.8 ± 35 km for longand short-period waves for the year 2010. Similarly, for 2011 the mean vertical wavelengths are found to be approximately −77.6 ± 30 and −59.2 ± 30 km for long and short wave periods, respectively, indicating that the observations over Kolhapur were dominated by upward-propagating waves. We use a full-wave model to simulate the response of OH emission to the wave motion and compare the results with observed values.

“…Therefore, spectral decomposition is here needed only to discriminate against tidal variations, where the Doppler e ect is unimportant. Gravity waves with vertical wavelengths smaller than about 12 km (Swenson and Gardner, 1998;Reisin and Scheer, 2001) are unobservable with the airglow technique.…”

“…The phase relationships of multiple airglow intensities or airglow temperatures located at different altitudes can oftentimes reveal whether a gravity wave's amplitude is increasing, decreasing, or constant (Reisin and Scheer, 2001;Liu and Swenson, 2003;Taori and Taylor, 2006;Vargas et al, 2007). Here we first show the results of phase difference of any two of the airglow intensities as a function of time in Fig.…”

“…The Krassovsky ratio is another quantity that the experimenters and modelers in the Aeronomy community oftentimes calculate from their observations or their modeling results (Krassovsky, 1972;Walterscheid et al, 1994;Makhlouf et al, 1995;Reisin and Scheer, 2001;Takahashi et al, 2011). It is a quantity that relates relative airglow intensity fluctuation to relative airglow temperature fluctuation.…”

a b s t r a c tThe gravity wave-induced secular variations and fluctuations of airglow intensity-weighted temperatures for OH(8,3) nightglow, O 2 (0,1) atmospheric band, and O( 1 S) greenline in the MLT region were simulated to study the wave effects' on airglow temperatures. They were investigated with a time-dependent OH Chemistry-Dynamics (OHCD) model and a Multiple Airglow Chemistry-Dynamics (MACD) model with a small-scale linear gravity wave packet. The largest wave-induced airglow temperature secular variations are found to be $ 0.8% in the O 2 (0,1) temperature and the largest wave-induced airglow temperature fluctuations are found to be $ 0.25% in the O( 1 S) temperature. We also investigated the phase relationships between the airglow intensities and temperatures. Our results show that the airglow intensities lead the airglow temperatures most of the time. Also, airglow located at a higher altitude leads the airglow located at a lower altitude, indicating a downward phase progression, which is consistent with the phase of the wave packet we used. The Krassovsky ratio for these airglow emissions were calculated and found to be decreasing with increasing altitude. The amplitude of the Krassovsky ratio for OH(8,3) airglow, O 2 (0,1) atmospheric band, and O( 1 S) greenline were $ 10, 6, and 4, respectively.
