Atmospheric waves on the southern polar regions (- 80° < LAT < -60°) traced by the O2(a1Δg) airglow at 1.27 μm have been detected on the OMEGA nadir maps. During the day O2(a1Δg) excited molecules are produced by the photolysis of ozone. They are deactivated by radiating most of the photons at λ = 1.27 μm or through collisions with CO2 molecules (quenching) for altitudes < 20-26 km where this process is dominant. In this paper we investigate the role of the CO2 quenching in the observed airglow intensity fluctuations and the hypothesis that the detected wave patterns trace gravity waves (GWs) activity.
