CB.S0TIVE
To csterzine the radiant power of a 30-40 kKiloton surface burst as a function
of wavelength end the fircball color teaperature as seen from an airborne station.
These objectives were to be accomplished by determining the atmospheric attenuat-
ion by an independent neasurement and correcting the power received at the iustrucent station aboard the aircraft,

The eprotrval distribution of the radiant power is obtained from a nedium
