Cover Story: Meteoroids entering Earth’s atmosphere generate both luminous trails and shock waves that are detected as low-frequency acoustic signals (infrasound) at ground arrays. The authors present the first openly accessible dataset of 71 regional meteor events simultaneously recorded by all-sky cameras and a dedicated infrasound array in Ontario, Canada. Each event entry provides trajectory data, acoustic waveforms, and atmospheric profiles, enabling robust analysis of shock generation, propagation, and energy deposition. By integrating optical and acoustic observations, this dataset offers a durable community resource supporting meteor physics, atmospheric acoustics, and planetary defense research. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525.
