Chapman's airglow mechanism resurrected?

Geophysical Research Letters, 1993
A reanalysis is summarized of a previously unquestioned, sole source of kinetic data, on the reaction of NaO with O‐atom. It is apparent that there are significant uncertainties in the kinetic mechanism of the experiments. Moreover, it appears plausible that these reaction rate data do not relate to NaO but rather to Na2O.

An assessment of twilight airglow inversion procedures using atmosphere explorer observations [PDF]

The aim of this research project was to test and truth some recently developed methods for recovering thermospheric oxygen atom densities and thermospheric temperatures from ground-based observations of the 7320 A O(+)((sup 2)D - (sup 2)P) twilight air ...

High‐Spatial Resolution Space‐Based Observations in the Upper Troposphere and Upper Mesosphere of Wavelike Features Produced by Hurricane Ian

Geophysical Research Letters
A new high‐spatial resolution camera on the International Space Station used OH nightglow in the H‐band to image the ground at an ∼70 m pixel footprint over an ∼280 km swath and maintained this resolution during its 1.5 s exposure.
