Description/Abstract:
THE AIM OF THIS PROJECT WAS TO MEASURE HIGH-ALTITUDE WIND VELOCITIES A ND DIFFUSION COEFFICIENTS IN THE ALTITUDE REGION BETWEEN 60 AND 150 KM . THE METHOD INVOLVED THE EJECTION OF A SODIUM VAPOR TRAIL FROM A CAJU N ROCKET AT DUSK OR DAWN TWILIGHT. THE SODIUM WAS SUNLIT, AND AS A RES ULT OF EMISSION OF RESONANCE RADIATION, WAS VISIBLE AGAINST A DARKENED BACKGROUND FOR ABOUT 20 MINUTES. THE TRAIL WAS PHOTOGRAPHED SIMULTANEO USLY FROM FOUR DIFFERENT SITES, ALLOWING FOR SUBSEQUENT TRIANGULATION TO DETERMINE THE ALTITUDE OF VARIOUS PARTS OF THE CLOUD. A MAJOR APPL ICATION OF THESE WIND AND DIFFUSION DATA, TAKEN AT DUSK AND DAWN FOLLO WING THE HIGH-ALTITUDE NUCLEAR TESTS, WAS TO AID IN DETERMINING THE DI SPOSITION OF THE NUCLEAR DEBRIS. THE MAIN OBJECTIVE WAS TO MEASURE WIND VELOCITIES AND DIFFUSION COEFFI CIENTS IN THE ALTITUDE REGION BETWEEN 60 AND 150 KM, BEFORE AND AFTER HIGH-ALTITUDE NUCLEAR DETONATIONS. A SECOND OBJECTIVE WAS TO DETERMINE WHETHER THE DETONATIONS HAD ANY EFFECT ON ATMOSPHERIC CIRCULATIONS AT HIGH ALTITUDE THAT WOULD PERSIST FOR HOURS. THE METHOD INVOLVED THE E JECTION OF A SODIUM VAPOR TRAIL FROM A CAJUN ROCKET AT DUSK OR DAWN TW ILIGHT. THE SODIUM WAS SUNLIT AND, AS A RESULT OF EMISSION OF RESONANC E RADIATION, WAS VISIBLE FOR ABOUT 20 MINUTES. THE TRAIL WAS PHOTOGRAP HED SIMULTANEOUSLY BY CAMERAS LOCATED ON JOHNSTON ISLAND AND SHIPS S-1 , S-2, AND S-4. THE WINDS WERE MEASURED IN THE NORMAL ATMOSPHERE ON 8 JULY 1962 BEFORE STAR FISH PRIME, ON 25 JULY BEFORE BLUE GILL PRIME, AND ON 3 NOVEMBER BEFORE TIGHT ROPE. DATA WAS OBTAINED AFTER STAR FISH PRIME, BLUE GILL TRIPLE PRIME AND AT THREE DIFFERENT TIMES FOLLOWING K ING FISH. A MAJOR CHANGE IN THE WIND PATTERN IN THE ALTITUDE REGION 80 TO 130 KM, WAS PRODUCED BY STAR FISH PRIME. ABOVE 100 KM THE WIND WAS TO THE SOUTH, EVIDENTLY AFFECTED BY THE MOTION OF FIELD-ALIGNED IONIZ ED MATERIAL. NO SIGNIFICANT CHANGE WAS CAUSED BY BLUE GILL TRIPLE PRIM E IN THE SAME ALTITUDE REGION. HOWEVER, SOME UNUSUAL WIND DIRECTIONS W ERE OBSERVED FOLLOWING KING FISH. INADDITION TO IDENTIFYING PERTURBATI ONS IN THE UPPER ATMOSPHERE, THE MEASUREMENTS PROVIDE DATA WHICH CAN B E APPLIED TO STUDIES OF DEBRIS MOTION FOLLOWING THE HIGH-ALTITUDE DETO NATIONS.
