Abstract :
Sodar and RASS are examples of remote sensing techniques used widely around the world today which are based on acoustic propagation and scattering. Acoustic tomography of the atmosphere, in comparison, has been used to a much lesser extent. However, acoustic tomography will probably be used more in the atmosphere in coming years. The authors give a short overview of different schemes for acoustic tomography of the atmosphere. Furthermore, they propose a new scheme of acoustic tomography of a stratified moving atmosphere. The main idea of this scheme is to reconstruct vertical profiles of temperature and wind velocity vector up to heights of about 10 km above the ground by measuring the time delay of sound signals from commercial airplanes at microphones located on the ground
