Natural and artificial impulsive sources in the atmosphere can generate infrasound, or very low frequency (f<20 Hz) acoustic waves, that can travel over long distances with minimal attenuation. Traditionally confined to ground-based sensors, the domain of infrasound sensing has expanded in recent years to include airborne platforms (e.g., balloons). Unlike other sensing modalities that might...
