The balloons were designed to carry two payload boxes, separated by a 100 meter tether. Each payload box contained a DiGOS DATA-CUBE, recording three InfraBSU infrasound microbarometers at 400 Hz. One microbarometer recorded true polarity of acoustic signals, another recorded reversed polarity, and flow filters covered both ports on the final microphone, preventing acoustic waves from registering on the device. This data set contains a combination of data from the first and second microphones. In subtracting the polarity-reversed data from the true-polarity data, we expect acoustic signals to remain intact and non acoustic noise sources (e. g. electromagnetic interference, vibration) to be removed from the data.
