Infrasonic Tracking of the Chelyabinsk Meteor
Abstract
The Infrasonic Energy, Nth Octave (INFERNO) energy estimator of Garces (2013) is used in conjunction with the PMCC4 array processing algorithm to refine the chronology and energetics of infrasonic signals from the Chelyabinsk Meteor. We concentrate on infrasound array data from the closest stations: I31KZ (Aktyubinsk, Kazakhstan), I43RU (Dubna, Russia), and KURK (Kurchatov, Kazakhstan), using the published satellite trajectory as a starting point. This study systematically applies standardized, self-similar, logarithmic time-frequency multiresolution algorithms to infrasonic data with the aim of improving the temporal and spatial resolution of the arrivals associated with the meteor's impact.
