GROUND-LEVEL MICROBAROGRAPHIC PRESSURE MEASUREMENTS FROM A HIGH-ALTITUDE SHOT

Abstract

Time records of incident and reflected overpressures from the high- altitude burst (Shot 10) of Operation Teapot were obtained at an array of ground stations. Modified Sachs' scaling to sea level for 1 kt gives overpressure results in agreement with an extension of the pressuredistance curve determined from canister data. Acoustic refraction did not appreciably alter the pressure- distance effects on this occasion. Shock-wave time parameters for this test were found to satisfy ordinary Sachs' scaling. An average pressure reflection factor of 0.92 was observed, but no correlation with surface parameters was obtained.
