International audience Inertia-gravity waves with very short vertical wavelength (λz ≤ 1000 m) are a very common feature of the lowermost stratosphere as observed by the 52MHz radar ESRAD (Esrange MST radar) in northern Scandinavia (67.88◦ N, 21.10◦ E). The waves are seen most clearly in radar-deriv...
