Herrin, E.T., Kim, T.S. and Stump, B.W. (2006). Evidence for an infrasound waveguide. Geophysical Research Letters 33: doi: 10.1029/2005GL025491. issn: 0094-8276.

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