On May 30, 2005, eight strongly dispersed infrasound signals were recorded at one seismo-acoustic array in the Republic of Korea. Phase-matched filtering Herrin Goforth, 1977 and a forward modeling technique were used to determine the nature of the dispersion. The most likely explanation for these dispersed infrasound signals is that the dispersion is due to propagation down a low-velocity waveguide This can be characterized as an ephemeral SOFAR layer in the atmosphere.
