Evaluation of a Generalized Least Squares Algorithm for Infrasound Beamforming with Coherent Background Noise [Dataset]

This dataset contains infrasound waveforms to accompany the peer-reviewed manuscript “Evaluation of a Generalized Least Squares Algorithm for Infrasound Beamforming with Coherent Background Noise” submitted for publication in the journal Geophysical Journal International by Jordan W. Bishop, Philip Blom, and Jeremy Webster. It contains the infrasound data used to create Figures 8 and 9 in the manuscript. Results using this data have previously been published as Blom (2019) and Blom (2024), for example, and we seek to release this data publicly for compliance with the journal’s Data Availability section. Seven of the waveform files contain infrasound recordings of the 2016 Forensic Surface Experiment recorded at a LANL infrasound array in St. George, UT, USA. The other ten recordings are of a 2020 bolide recorded at the International Monitoring System array I37NO in Norway.

Bishop、Philip Blom与Jeremy Webster提交至《Geophysical Journal International》期刊、等待同行评审的论文《相干背景噪声下次声波波束成形（infrasound beamforming）的广义最小二乘算法（Generalized Least Squares Algorithm）评估》。本数据集包含用于复现该论文中图8与图9的次声波数据。基于此数据得到的研究成果此前已发表于Blom(2019)与Blom(2024)等文献，本次公开发布本数据集以符合期刊对数据可用性章节的要求。其中7个波形文件包含2016年法医地表实验的次声波录音，该录音由部署于美国犹他州圣乔治市的LANL次声波台阵采集得到。剩余10条录音为2020年火流星（bolide）的次声波记录，采集自挪威国际监测系统（International Monitoring System）台阵I37NO。 LA-UR-25-24644 Bishop, J.W.、Blom, P.与Webster, J.，《相干背景噪声下次声波波束成形的广义最小二乘算法评估（Evaluation of a Generalized Least Squares Algorithm for Infrasound Beamforming with Coherent Background Noise）》，收录于《Geophysical Journal International》（审稿中）。 Philip Blom，《球形大气层次声传播建模——平流层配对事件分析》，发表于《J.
