Abstract:
Over the last two years, infrasound microphone arrays flown on the HASP have revealed a remarkably complex acoustic wave field in the stratosphere. While some of these signals are analogues for those seen on ground based arrays, others appear to be new to science. During the previous two HASP flights, however, the infrasound microphones have had inconsistent amplitude responses. Furthermore, interference from the HASP telemetry system or other payloads has created spurious signals in the infrasound data. During the HASP 2016, we seek to quantify the presence of spurious signals on stratospheric infrasound arrays, identify and mitigate the source of amplitude discrepancies during flight, and acquire additional observations of low frequency sounds. Results from this experiment will shed further light on the nature and variability of infrasound in the stratosphere as well as permit confident interpretation of the approximately 30 hours of acoustic data we have already collected.
