Paper Abstract

A ground-based instrument for measurement of perturbations of the rotational temperature and vertical column emission rate of the O2 atmospheric nightglow layer at 94 km and the OH Meinel layer at 86 km is described with special emphasis on its suitability as a remote field instrument. Ground-based instruments are needed in the detailed study of planetary scale dynamic effects in the upper atmosphere because they show detailed perturbation development in both solar and universal time that is missed by satellite-borne instruments. Ground-based instruments must be stable, accessible to but not dependent upon operator interaction, and inexpensive. The technique of interference filter spectral imaging has shown itself to satisfy these requirements when embodied in the instrument MORTI, a mesopause oxygen rotational temperature imager. SATI represents a complete re-design of MORTI in order to make it more flexible for ground-based networks. In particular, the cryogenic cooling was replaced by thermo-electric cooling, removing the requirement for daily attention, an OH channel was added that will allow comparison of perturbation amplitudes at two significantly different altitudes, and real-time temperature and emission rate readout was incorporated into the revised software.
