Аннотация:A new decomposition method (decomposition into N and U-waves) of infrasonic signals correspondingto partial reflection of N-wave sounding pulses from anisotropic atmospheric layers and recordedin areas of geometric shadow at large distances from explosions and volcanic eruptions is presented. The decomposition method makes it possible to determine the vertical gradients of the effective sound speed (sound speed plus wind speed in the direction of propagation) that are not available for determination by other methods.
