Free-field airblast parameters were measured from the detonation of a spherical 500-ton TNT charge. The charge was placed on the ground such that its height of burst would be one radius above the earths surface. Measured values of shock-wave arrival time, maximum overpressure, positive phase duration, overpressure impulse, dynamic pressure, and dynamic pressure impulses are presented as functions of ground range and are compared with predictions generated from scaled empirical and theoretical data. Results are compared with those from PRAIRIE FLAT.
