Infrasound Propagation Working Group Report

This report summarizes the activities and recommendations of the Infrasound Propagation Working Group (IPWG). The working group conducted background research, gathered input from the broader infrasound community, and had an in-person meeting to 1) assess the current state of infrasound propagation modeling and 2) make a number of recommendations for improvements. The recommendations provided at the end of this report will provide substantial improvements to infrasound propagation modeling and will result in advances in nuclear treaty monitoring and related efforts.
