Abstract

A simple method has been proposed to determine acoustic-gravity wave (AGW) properties at mesosphere heights from measurements of VLF radio signals. For relatively short paths (less than ∼ 2000 km long), simple relations are obtained for estimation of AGW neutral density fluctuation from measurements of amplitudes of radio signals. In the wave-hop approximation, we relate the fluctuations in radio signal reflection height with AGW-induced vertical displacement of an elementary volume of atmospheric gas. Using these relations, we can recover some properties of AGWs at mesosphere heights.
