AIR TEMPERATURE MEASUREMENTS OVER SEVERAL SURFACES

Abstract

Preshock air-temperature measurements in the vicinity of a nuclear detonation are reported. Although no data were obtained for close-in stations over water, asphalt, and desert, somewhat interesting but unusual results were obtained for stations of simulated terrain such as plots of ivy plants, fir boughs, wood, and concrete. The maximum air temperatures above ambient were found to be in excess of 1,500 deg C over all plots. Furthermore, an increase in maximum air temperatures with elevation was found over all plots. Results of supporting high speed photographic coverage and gas analysis of air above irradiated plots are reported. An attempt to explain the results is given despite the lack of sufficient data.
