Data from: Upper atmosphere heating from ocean-generated acoustic wave energy

Daniel C. Bowman & Jonathan M. Lees
Colliding sea surface waves generate the ocean microbarom, an acoustic signal that may transmit significant energy to the upper atmosphere. Previous estimates of acoustic energy flux from the ocean microbarom and mountain/wind interactions are on the order of 0.01 to 1 mW/m2, heating the thermosphere by tens of degrees Kelvin per day. We captured up going ocean microbarom waves with a balloon borne infrasound microphone; the maximum acoustic energy flux was approximately 0.05 mW/m2. This...

Data from: Explosion-generated infrasound recorded on ground and airborne microbarometers at regional distances

Eliot F. Young, Daniel C. Bowman, Jonathan M. Lees, Viliam Klein, Steven J. Arrowsmith & Courtney Ballard
Recent work in deploying infrasound (low frequency sound) sensors on aerostats and free flying balloons has shown them to be viable alternatives to ground stations. However, no study to date has compared the performance of surface and free floating infrasound microbarometers with respect to acoustic events at regional (100s of kilometers) range. The prospect of enhanced detection of aerial explosions at similar ranges, such as those from bolides, has not been investigated either. We examined...
