Abstract
MLT (Mesosphere and Lower Thermosphere) region is known to be dynamically complex, probably due to the tides and gravity waves that propagate upward from below. The emission rate and temperature fluctuations related to these waves are observed using a ground-based optical instrument, called SATI (Spectral Airglow Temperature Imager). The SATI instrument was installed and has been in routine operation in Resolute Bay (74.68 N, 94.90 W) since November 2001. By spectrally monitoring the O2 (0-1) atmospheric band from ~ 94 km and OH (6-2) Meinel band nightglow from ~ 87 km, SATI measures the rotational temperatures and the emission rates of the terrestrial nightglows. From the analysis of 2001/2002 winter season data, dominant and coherent 4-hr oscillations were observed in both the O2 and OH airglow emission rates and rotational temperatures.
