Several sources of interest often generate both low‐frequency acoustic and seismic signals
due to energy propagation through the atmosphere and the solid Earth. Seismic and …

Infrasound waveforms generated by natural and anthropogenic phenomena contain
important clues about the size and nature of the event. We show that sensors on balloons in …

In this chapter, an overview of infrasound propagation modeling is presented. The
atmosphere as a propagation medium is discussed with an emphasis on the various …

In recent years, high-altitude infrasound sensing has become more prolific, demonstrating
an enormous value especially when utilized over regions inaccessible to traditional ground …

The receiver-to-source backazimuth of atmospheric infrasound signals is biased when cross-
winds are present along the propagation path. Infrasound from 598 surface explosions from …

A helium‐filled mylar balloon carrying a smartphone and infrasound sensors ascended to a
stratospheric height of 35 km over the surface detonation of a chemical explosive, with a …

Infrasonic waves are influenced by variations in the density, pressure and temperature as
well as the ambient winds. Modelling infrasonic propagation can be challenging due to the …

This study uses low‐frequency, inaudible acoustic waves (infrasound) to probe wind and
temperature fluctuations associated with breaking gravity waves (GWs) in the middle …

The relations describing the reflection of three-dimensional acoustic ray paths impinging on
a non-flat surface are derived and used to approximate the propagation of infrasonic signals …

Infrasonic signals refracted by thermal gradients in the rarefied upper atmosphere are
modeled using a combination of ray tracing and weak shock theory to develop an …
