The instrument is designed to image near-infrared emissions from the OH(6-2) band of airglow. The main objective is to study the morphology of the airglow layer at 90 km of altitude in the mesosphere. We expect to see how gravity waves and meteors interact with the layer in order to get a better understanding of the weather up there. Filter-ratio temperatures will be retrieved and compared to what we measure with the 1m Ebert-Fastie spectrometer (Silver Bullet).
