Micro-Wave Radio Robot Reports Weather (Jan, 1936)

Micro-Wave Radio Robot Reports Weather

FAR above the heights reached by Settle and Piccard, “sounding balloons” rise into the stratosphere, unmanned, but with delicate apparatus to report the atmospheric conditions they encounter. That shown above is called a “meteor-graph” and a thermometer, barometer and hygrometer, inside the shell, control the oscillations from a radio circuit. These signals are automatically recorded on a revolving drum at the receiver, and serve for study of the weather in the uppermost atmosphere to determine its effect, if any, on that prevailing below.
