Here, we present a protocol for the analysis of barometric pressure data from multiple stations for the globally propagating spherical shockwaves generated by catastrophic explosions. We demonstrate the analytical procedure using the Tonga underwater volcano eruption of January 2022. We also present a protocol to make a data recorder using off-the-shelf electronic components for barometric pressure measurements at ∼1 Hz. The data recorder and the analysis protocol can be used to study similar future catastrophic events. For complete details on the use and execution of this protocol, please refer to Li (2022).1.

Shock Waves
When the source's speed approaches the speed of sound, constructive interference between successive wavefronts emitted by the source occurs immediately behind it. Initially, scientists believed that this constructive interference would result in such high...

Variation of Atmospheric Pressure
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
