“…Probably the first atmospheric observation was made in the headglow from a rocket‐borne iron carbonyl release [ Best et al , 1972], and the spectrum obtained was essentially identical to that seen in the present studies.…”

[1] There continue to be surprises in the identification of the terrestrial nightglow components. Comparison of the nightglow as measured in astronomical sky spectra and Optical Spectrograph and Infrared Imager System (OSIRIS)/Odin orbiter data with that on FeO emission in meteor trains and laboratory experiments demonstrates that this emission is an important part of the nightglow, appearing as a quasi-continuum between 540 and 680 nm, with maximum intensity at 595 nm. In order to study the FeO emission, account must be taken of other nearby emissions, including the 589 nm sodium emission lines, and the underlying 8−2 OH Meinel band. The temporal behavior of the three emissions is normally closely related, but strong excursions can occur, which could provide valuable information on atmospheric processes. The temporal behavior of the FeO and OH emissions was compared to model results from the one-dimensional and time-resolved model FeMOD, which describes the iron chemistry in the mesosphere/ lower thermosphere. Further observations and comparisons with satellite and lidar data as well as models will make it possible to improve our understanding of mesospheric chemistry, meteor ablation, and the role of iron in the atmosphere.

“…In the present analysis, a wedge distribution (decreasing linear weights from 10 to 1) of vibrational level populations has been assumed for the laboratory pressures while a flat distribution of equal weights has been used to simulate the vibrational distribution at mesospheric pressures levels appropriate to the satellite observations. In the future, valuable information could be obtained from rocket releases into the mesosphere that generate NiO * vapour trails using techniques similar to those employed by Best et al (1972) to generate FeO * emissions.…”

Abstract. The recent finding of an orange spectral feature in OSIRIS/Odin spectra of the night airglow near 87 km has raised interest in the origin of the emission. The feature was positively identified as the chemiluminescent FeO * emission where the iron is of meteoric origin. Since the meteorite source of atomic metals in the mesosphere contains both iron and nickel, with Ni being typically 6 % of Fe, it is expected that faint emissions involving Ni should also be present in the night airglow. The present study summarizes the laboratory observations of chemiluminescent NiO * emissions and includes a search for the NiO * signature in the night airglow. A very faint previously unidentified "continuum" extending longwave of 440 nm has been detected in the night airglow spectra obtained with two space-borne limb viewing instruments. Through a comparison with laboratory spectra this continuum is identified as arising from the NiO * emission. The altitude profile of the new airglow emission has also been measured. The similarity of the altitude profiles of the FeO * and NiO * emissions also suggests the emission is NiO as both can originate from reaction of the metal atoms with mesospheric ozone. The observed NiO * to FeO * ratio exhibits considerable variability; possible causes of this observed variation are briefly discussed.

The recent finding of an orange spectral feature in OSIRIS/Odin spectra of the night airglow near 85 km has raised interest in the origin of the emission. The feature was positively identified as the chemiluminescent FeO^* emission where the iron is of meteoric origin. Since the meteorite source of atomic metals in the mesosphere contains both iron and nickel, with Ni being typically 6% of Fe, it is expected that faint emissions involving Ni should also be present in the night airglow. The present study summarizes the laboratory observations of chemiluminescent NiO^* emissions and includes a search for the NiO^* signature in the night airglow. A faint previously unidentified "continuum" extending longwave of 440 nm has been identified in night airglow spectra obtained with two space-borne limb viewing instruments and through a comparison with laboratory spectra this continuum is identified as arising from the NiO^* emission. The FeO^* and NiO^* emissions both originate from a reaction of the metal atoms with mesospheric ozone and so support the presence of NiO^* in the night airglow
