Description/Abstract:
THE PURPOSE OF THIS PROJECT WAS TWOFOLD: FIRST, TO DOCUMENT THE EVOLUT ION OF ATOMIC CLOUDS DURING THE TEAPOT SERIES IN ORDER TO DEFINE THE R ATE OF RISE, MAXIMUM HEIGHT, VERTICAL DEPTH OF MUSHROOM, DIMENSIONS OF STEM AND VOLUME, FOR A PERIOD UP TO 20 MINUTES AFTER BURST WHEN PHOTO GRAPHICALLY FEASIBLE; SECOND, TO CORRELATE THE METEOROLOGICAL DATA WIT H THE AVAILABLE CLOUD DATA ON PAST NEVADA TEST SERIES AS WELL AS THE T EAPOT SERIES. OPERATING COMMANDS, IN PARTICULAR THE STRATEGIC AIR COM MAND AND THE AIR DEFENSE COMMAND, HAVE INDICATED A NEED FOR SUCH INFOR MATION RELATIVE TO OFFENSIVE AND DEFENSIVE TACTICS. PHOTOGRAPHIC DATA WERE COLLECTED AND ANALYZED BY EDGERTON, GERMESHAUSEN AND GRIER. ARMY MAP SERVICE PARTICIPATED IN SHOTS HA, POST, AND MET TO CHECK OUT A PH OTOGRAPHIC METHOD OF CLOUD VOLUME DETERMINATION BY A STEREOSCOPIC PROC EDURE. THE U. S. WEATHER BUREAU AND AIR FORCE CAMBRIDGE RESEARCH CENT ER EFFECTED THE CORRELATION OF CLOUD DATA WITH ATMOSPHERIC PARAMETERS AND MADE THEODOLITE OBSERVATIONS OF CLOUD RISE AND HEIGHT ON EACH SHOT . STRATEGIC AIR COMMAND (PROJECT 40.5) PHOTOGRAPHED THE RISING CLOUD FROM DIRECTLY ABOVE THE BURST AT SHORT TIME INCREMENTS AFTER H-HR. PH OTOGRAPHIC AND THEODOLITE DATA WERE COLLECTED ON 14 SHOTS. ANALYSIS O F WEATHER PARAMETERS AFFECTING CLOUD HEIGHTS ATTAINED DOES NOT SUGGEST ANY CLEAR-CUT DEFINITIONS WITH THE EXCEPTION OF THE TROPOPAUSE DAMPEN ING EFFECT. APPLICATION OF CURRENT THEORIES HAS BEEN INVESTIGATED AND THE RESULTS COMPARED. ARMY MAP SERVICE VOLUME ANALYSIS WAS NOT FEASI BLE ON THE HIGH ALTITUDE SHOT BECAUSE OF LACK OF DENSITY OF THE SMOKE RING. VOLUME ANALYSIS WAS NOT FEASIBLE ON SHOT POST (PREDAWN) BECAUSE OF LACK OF LIGHT. ON SHOT MET NONSYNCHRONIZATION OF PHOTO PAIRS DID NOT PERMIT A FEASIBILITY EVALUATION.
