International audience Using absorption data measured by imaging ri-ometer for ionospheric studies (IRIS) located at the South Africa National Antarctic Expedition (SANAE), Antarctica (72 • S, 3 • W), we extracted the parameters of gravity waves (GW) of periods between 40 and 50 min during late win-...
