The Role of Source Geometry and Atmospheric Propagation in Global Bolide Infrasound Detectability
Miro Ronac Giannone, Elizabeth A. Silber
Global infrasound monitoring provides a persistent means of detecting energetic bolide atmospheric entries, complementing optical observations and extending coverage over remote re…
Shock wave formation in the thermosphere by an earthgrazing fireball: Empirical evidence for volatile-enhanced hydrodynamic shielding
Elizabeth A. Silber, Denis Vida, Miro Ronac Giannone +7
Hydrodynamic shielding is a theoretically well-established but observationally elusive and experimentally difficult-to-replicate phenomenon with implications that extend far beyond…
Multi-Arrival Infrasound from Meteoroids: Fragmentation Signatures versus Propagation Effects in a Fine-Scale Layered Atmosphere
Igor P. Chunchuzov, Oleg E. Popov, Elizabeth A. Silber +1
Infrasonic signatures of meteoroid fragmentation are frequently ambiguous: do multiple arrivals signify a complex breakup or merely the distorting effects of a layered atmosphere?…
Effect of a Fine-Scale Layered Structure of the Atmosphere on Infrasound Signals from Fragmenting Meteoroids
Igor P. Chunchuzov, Oleg E. Popov, Elizabeth A. Silber +1
We investigate the influence of a fine-scale (FS) layered structure in the atmosphere on the propagation of infrasound signals generated by fragmenting meteoroids. Using a pseudo-d…
