Characterization of Predicted Infrasonic Phases For IS59, Hawaii

Abstract:

The atmosphere is a dynamic and complex medium, and infrasonic waves traveling through this medium will be strongly affected by its properties. The wind field, temperature, and composition of the atmosphere up to heights of 150 km will determine how sound waves are propagated between a source and a receiver. We integrate acoustic wave propagation models, the Naval Research Laboratory NRL Horizontal Wind Model HWM93, the NRL Mass Spectrometer and Incoherent Scatter MSIS90 atmospheric model, and the United Kingdom Meteorological Office UKMO Correlative Analyses to investigate the effects of atmospheric variability on the types of infrasonic phases that may be observed at CTBT array IS59 in Hawaii. Array IS59 Garces and Bass, 2000 this issue started recording and archiving infrasonic data in May 25, 2000, and has recorded a variety of regional and distant events. We use the results of our theoretical and data assimilation work to characterize the response of IS59 so that it possible to associate and locate events using multiple arrays.
