“…There have been many extensive theoretical and experimental investigations of this emission. The excitation process in the nighttime terrestrial atmosphere is generally assigned to the reaction [Bates and Nicolet, 1950;Valance Jones, 1973;LeTexier et al, 1987;Lopez-Moreno et al, 1987]…”

Nighttime morphological maps of the hydroxyl emission (8-3 band) measured by the Visible Airglow Experiment on board the Atmosphere Explorer E satellite are presented for solstice and equinox conditions. The volume emission rate profile of the emission was determined by inverting satellite perigee observations. This profile was later used to convert limb measurements into zenith intensities of the emission. A theoretical model has been used to correct twilight observations for the presence of the thermospheric O+(2P) emission at 7320-7330 •. The derived morphology agrees well with ground based measurements and theoretical simulations.

“…Although the altitude dependences are similar to those observed for some of the cases, the absolute flux values are far too small to explain the observed airglow emission. CO2 molecules have a strong 4.3m band (JONES, 1973). If the observed high altitude airglow component were due to CO2, the brightness of the 4.5m photometric band would be at least several times larger than that of the 2.8um band in the corresponding altitude range.…”

Near Infrared airglow was observed in the altitude range 80-210km at a mid latitude (300N) in the wavelength region between 2um and 5um. Two airglow components were found. One component is strong in the broad wavelength range at altitudes lower than 100km, which is considered to be due to OH Meinel bands, whereas the other component was detected in the altitude range higher than 110km. The intensity of the latter is too strong to be interpreted in terms of a current model of the thermosphere. If this is attributed to the 2.8um band (4v=2) of NO, the density profile of excited nitrogen atoms N(2D) can be derived from the reaction N(2D)+O2-NO+O. The absolute density thus derived is considerably higher than that obtained from NI (5,200A) airglow and that based on a thermospheric model.

“…Using the method and parameters by Vallance Jones (1973), the intensity of OH airglow was calculated assuming a rotation temperature of 200 K. in Fig. 3, a thick line shows the model of the sky brightness obtained by summing OH lines in the 0.1 /urn bandwidth.…”

The atmospheric airglow is thought to have a narrow window at 2.4 jmin, which corresponds to the wavelength gap between the fundamental and the first overtone of the OH vibration bands. In order to confirm this window, we analyzed data of past balloon experiments, and found that the sky brightness, k I\, at 2.4 jmm amounted to (7±2)X 10 10 W cm -2 sr" 1 or -15.5 mag arcsec" 2 . This level is considerably higher than expected. It can be explained, however, by assuming the nonequilibrium and partially high rotation temperature for OH radicals. This mechanism suggests that the OH window is shifted to longer wavelengths if the emission of other molecules and telescope itself is taken into account.
