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.
