“…The SATI instrumental concept and optical configuration is described in detail by Sargoytchev et al (2004). The instrument uses two interference filters, one centred at 867.689 nm (in the spectral region of the O 2 Atmospheric (0-1) band) and the second one centred at 836.813 nm (in the spectral region of the OH Meinel (6-2) band).…”

Abstract. The presence of planetary wave type oscillations at mid-latitudes in the mesosphere/lower thermosphere region has been investigated using airglow observations. The observations were taken with a Spectral Airglow Temperature Imager (SATI) installed at Sierra Nevada Observatory (37.06 • N, 3.38 • W) at 2900 m height. Airglow data of the column emission rate of the O 2 Atmospheric (0-1) band and of the OH Meinel (6-2) band and deduced rotational temperatures from 1998 to 2007 have been used in this study. From these observations a climatology of planetary wave type oscillations at this location is inferred. It has been found that the planetary wave type oscillations of 5-day period is predominant in our data throughout the year, with activity greater than 50% during March/April and October/November months. The planetary wave type oscillations of 2-day period is predominant during both solstices, being predominant during winter solstice in O 2 while a 10-day oscillation appears throughout the year with activity around 20% and with maximum activity during spring and autumn equinoxes. The 16-day oscillation has maximum occurrence during autumn-winter while its activity is almost disappeared during spring-summer. No clear seasonal dependence of the amplitude of the planetary wave type oscillations was observed in the cases considered in this study.The waves simultaneously detected in the rotational temperatures deduced from both OH and O 2 emissions usually Correspondence to: M. J. López-González (mariajose@iaa.es) show an upward energy propagation and are affected by dissipation processes.

“…These matters are currently being investigated in order to make a quantitative estimation of these errors (see Sargoytchev et al, 2004). Sargoytchev et al (2004) also study the problems associated with the fitting of the lines of the Q branch of the OH(6-2) band. Some of these difficulties are discussed in the next section.…”

Abstract. More than 3 years of airglow observations with a Spectral Airglow Temperature Imager (SATI) installed at the Sierra Nevada Observatory (37.06 • N, 3.38 • W) at 2900 m height have been analyzed. Values of the column emission rate and vertically averaged temperature of the O 2 atmospheric (0-1) band and of the OH Meinel (6-2) band from 1998 to 2002 have been presented. From these observations a clear seasonal variation of both emission rates and rotational temperatures is inferred at this latitude. It is found that the annual variation of the temperatures is larger than the semiannual variation, while for the emission rates the amplitudes are comparable.

“…The SATI instrumental concept and optical configuration was originally developed as the Mesopause Oxygen Rotational Temperature Imager (MORTI) instrument (Wiens et al, 1991). The new adaptation as SATI is described in detail by Sargoytchev et al (2004). The instrument uses two interference filters, one centred at 867.689 nm (in the spectral region of the O 2 Atmospheric (0-1) band) and the second one centred at 836.813 nm (in the spectral region of the OH Meinel (6-2) band).…”

Abstract. Airglow observations with a Spectral AirglowTemperature Imager (SATI), installed at the Sierra Nevada Observatory (37.06 • N, 3.38 • W) at 2900-m height, have been used to investigate the presence of tidal variations at mid-latitudes in the mesosphere/lower thermosphere region. Diurnal variations of the column emission rate and vertically averaged temperature of the O 2 Atmospheric (0-1) band and of the OH Meinel (6-2) band from 5 years (1998)(1999)(2000)(2001)(2002)(2003) of observations have been analysed. From these observations a clear tidal variation of both emission rates and rotational temperatures is inferred. It is found that the amplitude of the daily variation for both emission rates and temperatures is greater from late autumn to spring than during summer. The amplitude decreases by more than a factor of two during summer and early autumn with respect to the amplitude in the winter-spring months. Although the tidal modulations are preferentially semidiurnal in both rotational temperatures and emission rates during the whole year, during early spring the tidal modulations seem to be more consistent with a diurnal modulation in both rotational temperatures and emission rates. Moreover, the OH emission rate from late autumn to early winter has a pattern suggesting both diurnal and semidiurnal tidal modulations.
