Primary calibration for airborne infrasound utilizing the vertical gradient of the ambient pressure

The demand for reliable and traceable measurements of airborne infrasound has risen, one major application being the International Monitoring System run by the Comprehensive Nuclear-Test-Ban Treaty Organization. However, the current calibration methods do not sufficiently cover the infrasound freque...
