New studies using lidar, radar, microwave spectrometer, and mesospheric airglow observations complemented by satellite measurements help better determine the interaction between atmospheric layers from the ground to the mesosphere and the influence of atmospheric waves on the mean flow. It is expected that further developing multi-instruments platforms would improve gravity wave parameterizations and enlarge the science community interested in operational infrasound monitoring. In a higher frequency range, the infrasound monitoring system also offers a unique opportunity to provide, in near-real time, continuous relevant information about natural hazards with high societal impact, such as large volcanic eruptions, surface earthquakes, meteoroids, and bright fireballs.
We invite contributions on recent studies characterizing infrasound sources or large-scale atmospheric phenomena, including presentations utilizing acoustic waves to probe the atmosphere. Results and advances in acoustic propagation modeling and innovative instrumentation, which also encompasses the extension of regional array networks, are welcome. We also invite studies of the role that infrasound and acoustic-gravity waves play in the coupled Earth’s crust – ocean – atmosphere system and, in particular, in ionospheric manifestations of physical processes in the ocean and in the solid Earth. Contributions highlighting data products and services for civilian and scientific applications utilizing or supplementing infrasound observations are particularly encouraged.
