Abstract : Eighteen microbarographs recorded airblast from PRAIRIE FLAT and three 1. 2-ton HE blasts. Sensors were spaced at 1- and 2-mite intervals at distances from 119 to 141 miles west of the bursts, to record ozonosphere ducted propagations, hopefully in a caustic. Results showed that there were humps in the amplitude-versus-distance curve which were observed to pass through the array and changed from shot to shot. These appear to be the caustic, which was broken up by atmospheric irregularities, and resulted in approximately double amplitudes over 6- to 8-mile bands. Amplitudes were proportional to the 0.425 power of apparent blast yield, which was close to the 0.40 value previously measured.
