330-PS-3256 (45898 AC): Indian Springs Air Force Base, Nevada, April 20, 1952. Exact weather information is a prime necessity during atomic test periods. To obtain information concerning air pressure, temperature and humidity, these captive, helium-filled “Kytoon” balloons, as shown here, are supplied by the USAF’s Air Weather Service during the Atomic Energy Commission’s periodic atomic tests at the Nevada Providing Grounds. Kytoon Balloons are sent aloft before each nuclear test, and are hauled down minutes before the actual detonation occurs. Last minute weather information is thus relayed by remote control to the A.K.C. Test Director at the Proving Grounds Control Point. Such data is used to predict subsequent paths of radio-active clouds through the atmosphere. Photograph released March 16, 1953. (5/5/2015).
