“…A meridian scanning photometer system was used by Takahashi et al [1985] to study several lower thermospheric emission layers simultaneously. Spectroscopic studies of the near-IR OH bands have been reported by Krassovsky [ 1972], Krassovsky andShagaev [1974, 1977], Armstrong [1975], Noxon [1978], Takeuchi et al [1979], Myrabo et al [1983Myrabo et al [ , 1984 The physical and chemical processes involved with AGWs propagating through the OH airglow layer have been discussed by Krassovsky and Shefov [1976]. Krassovsky [1972] introduced the ratio n = [am]/[aT/T] and deduced expected values for r/, assuming adiabatic temperature changes for an assumed chemical model.…”

Ground‐based observations of lower thermospheric emission originating from OH(8‐3) rotation lines P1,2 at 7316.4 Å and P2,3 at 7330 Å were made with an intensified imaging Fabry‐Perot interferometer from Santa Cruz, California, on September 25 and 26, 1987, during a CEDAR campaign. The rotational lines were imaged simultaneously from four different atmospheric volume elements which were separated by ∼15 km north to south and ∼30 km east to west. Two types of analysis are performed on the data. First, traditionally observed temporal structure in the rotational temperature showed acoustic gravity wave‐like periods which are compared to other experimental data. Spectral analysis on the data shows the traditional gravity wave characteristics for specific periods in four separated atmospheric volumes which were sampled simultaneously. Second, the simultaneous multiple‐point sample provides a measurement of horizontal phase velocity. Spectral components of temperature variation exhibited phase coherence in all four spatial regions, indicating wave phenomena of length scales ≫30 km. Gravity wave η versus period data are compared with the theories of Schubert and Walterscheid (1988) and Hickey (1988a, b).

“…Also, the six pairs of lines are spaced enough apart to be selected by a narrow band interference filter. Furthermore, although the OH Meinel bands such as (6-2) and (8-3) are also alternative spectral lines [28], they have not yet been installed in the current prototype due to limited funds, but will be added in future research.…”

Ground-based airglow imaging interferometer Part 1: instrument and observation

A ground-based airglow imaging interferometer (GBAII) is proposed to measure simultaneously the temperature and wind in the mesopause region by using airglow emissions of the O₂(0-1) band. Since it employs a wide angle Michelson interferometer with a large air gap, combined with the rotational temperature measurement, both the phase and spectral information can be obtained from the imaging results. Based on the optimization and calibrations for the optical system in the laboratory, we developed and assembled a prototype of a GBAII, and carried out one observation at the observatory of Xi'an University of Technology on 12 June 2012. The observed temperatures fall mainly on the range of 167-196 K, while both the zonal and meridional winds faintly show the feature of half-day oscillation. The consistent trends between the observation results and the standard atmospheric models suggest that the GBAII has achieved our basic design goals.
