Book excerpt: Surface level and aboveground static overpressures, near-surface differential pressures (pitot-tube), and nearsurface total pressures were measured on a low-burstheight nuclear explosion (Shot Priscilla) 700 feet, 36.6 kt). Gages were placed at ground ranges from 450 feet to 4,500 feet, with a concentration of measurements in the highpressure region. Blast switches, which measured arrival time only, were placed at several ranges, the closest at 100-foot range. Usable records were obtained on 39 of the 47 electronic channels. A precursor wave formed near 500-foot ground range, and dissipated between 2,000 and 2,500 feet. Shot Priscilla shock velocity agrees with the ideal except between 500- and 2,000-foot ranges where it exceeds the ideal. Computed preshock arrival surface temperatures are significantly higher than those computed for Shot 12, Operation Teapot. Differential pressure wave-form classifications based on the degree of deviation from the corresponding overpressure wave form indicates that at close-in scaled ground ranges total-head pressure wave forms follow fairly closely those of the overpressure. The greatest deviations are concentrated between 450 and 900 feet scaled ground range and 100 and 300 feet scaled burst height.
