Short summary

This paper presents a ground-based, short-wave infrared camera system for measurements of the OH airglow originating in the middle atmosphere. The camera has a high temporal and spatial resolution of 0.5 s and 200 m (at 90 km height), which allows for detailed observations of atmospheric waves and other transient phenomena. Details regarding the instrument, calibration and preprocessing are discussed exemplarily for an event of two superposing gravity waves with associated instability structures.
