Two ground-based instruments called SATI (Spectral Airglow Temperature Imager) to monitor the airglow temperature and emission rate in the polar MLT (Mesosphere and Lower Thermosphere) region have been in operation at Resolute Bay (74.68 N, 94.90 W) and at Eureka (80.00 N, 86.25 W) since November, 2001, and November, 2007, respectively. The Eureka SATI was developed for the CANDAC (Canadian Network for the Detection of Atmospheric Change) project. The SATI instrument is a two-channel, Fabry-Perot spectrometer, and measures the OH and O2 airglow emissions at 87 km and 94 km, where the airglow emission peaks are located, from the respective annular field of views. These horizontal and vertical measurements are used to investigate the atmospheric wave dynamics in the MLT region at the two locations. The results on the wave propagation characteristics are compared and discussed.
