Abstract:

Radiosonde observations, or RAOBS as they are termed, are made to determine the pressure, temperature, and humidity from the surface to the point where the balloon bursts. The radiosonde consists of meteorological measuring elements coupled to a radio transmitter and assembled into a small lightweight box. The device is carried aloft by a balloon filled with hydrogen or helium gas. Included in the train is a small parachute to slow the descent of the instrument after the balloon bursts, thereby minimizing the danger of injury to life and property. As the balloon rises, measurements of pressure, temperature, and relative humidity are transmitted to a ground station where the data are recorded automatically. This handbook deals primarily with those procedures necessary in taking the RAOB. Author
