Abstract: 
An empirical understanding of planetary scale perturbations in the upper atmosphere is most effectively gained by the complementary use of both satellite and ground-based instrumentation. Limb observations from space provide vertical information and broad global coverage, while ground-based observations provide detailed system development in both solar and universal time. Ground-based instruments must be stable, accessible to but not dependent upon operator interaction, and inexpensive. The technique of interference filter spectral scanning has shown itself to satisfy these requirements when embodied in the instrument MORTI, a mesopause oxygen rotational temperature imager. MORTI has been especially useful in studies of fluctuations of the temperature and emission rate of the O2 Atmospheric airglow layer. SATI represents a complete redesign of the MORTI concept in order to make it an even better instrument for ground-based networks. The major new features are the replacement of cryogenic by thermo-electric cooling, real time temperature and emission rate readout, remote operation, and the addition of an OH channel. Examples of spectral airglow images taken with SATI are presented and its potential use in the COSTEP PSMOS project (planetary scale mesopause observing system) is discussed. (C) 1997 COSPAR.
