Yield estimates were obtained during Hardtack Phase I for five detonations at distances ranging from 11 to 25 miles. The greatest error in yield was obtained at 22.5 miles where the ratio of indicated yield to actual yield was about 2.5. For a lapse condition, it is estimated that automatic yield indicators will nearly always indicate within a factor of 2 or 3 of the actual yield within the range to 0.1 psi peak overpressure (about 30 miles for 1 mt). Under strong low-level temperature inversions (rapid increase in temperature with increase in height above the surface) at Nevada Test Site, automatic yield indicators functioned properly on 11 shots on Operation Hardtack, Phase II. Yields ranged from 0.62 ton to 6.5 kt and distances ranged from 2 to 13 miles. On eight of these events, indicated yields were within a factor of 2 of actual yields. Greater errors on the three other events were caused by interference effects resulting from the inversion conditions. This and other blast-wave measurements indicate that factor-of-2 yield estimates can be obtained by the AYI about 70 percent of the time under strong inversion conditions within the range of 0.1 psi.Mode of access: Internet.This bibliographic record is available under the Creative Commons CC0 "No Rights Reserved" license.
