SPECTRAL DISTRIBUTION OF IRRADIANCE WITH HIGH TIME RESOLUTION
Abstract
A multichannel recording spectrometer with high time resolution in the spectral range of 2,500 to 25,000 A was used to measure the spectral distribution of the irradiance as a function of time received at two locations for Shot Cherokee and at one location for Shot Zuni. Due to a large drop error, the point of detonation occurred outside of the field of view of both instruments on Cherokee. The spectral distribution of the irradiance received at the time of the second maximum for Shot Zuni showed that a large portion of the energy was in the infrared region of the spectrum. The distributions at other times are not reported, since the irradiance levels were much lower than expected because of considerable cloud obscuration of the Fireball. (Author)
