On Micrometeorology

Micrometeorology in the Tropics *

“…(Findeisen's [2] studies on the "Micro-physics of Cloud," and Haurwitz' [3] on the micro-barometric oscillations at Blue Hill are examples of pre-war studies on free-air micrometeorology.) The work reported by H. K. Schilling [4] and his co-workers of Pennsylvania State College and the exhaustive work done by the Army and collaborating meteorologists on San Jose Island where permanent micrometeorological stations have been installed evidenced the military interest and need.…”

OPERATION TUMBLER, Nevada Proving Grounds. Project 8.6. Sound Velocity Changes near the Ground in the Vicinity of an Atomic Explosion

“…The 500 cps sine waves amplitude modulate a 10 Ke carrier and the modulated wave then enters the terminals of an electro- acoustic transmitting transducer.l1 This loudspeaker's diaphragm then emits a sound wave which is received by the di gm of another transducer.1 6 The interdiaphragm distance is 3 ft. -. i The modulated wave from the receiving transducer then travels over wires to the demodulator.…”
