The radiosonde contains instruments capable of making direct in-situ measurements of air temperature, humidity and pressure with height, typically to altitudes of approximately 30 km. These observed data are transmitted immediately to the ground station by a radio transmitter located within the instrument package.

Radiosonde Observations ... Since the late 1930s, upper air observations have been made by the NOAA National Weather Service (NWS) with radiosondes. The radiosonde is a small, expendable instrument package that is suspended 25 meters (about 80 feet) or more below a large balloon inflated with hydrogen or helium gas.

A radiosonde is a small box-like instrument that is carried into the upper atmosphere by balloon. As it travels upward, it transmits meteorological measurements to ground stations. Radiosondes measure temperature with a thermometer, humidity with a hygrometer, and air pressure with a barometer.

The radiosonde flight can last in excess of two hours, and during this time the radiosonde can ascend to over 35 km (about 115,000 feet) and drift more than 200 km (about 125 miles) from the release point.

Data from the radiosonde is interpreted at the launching station and entered into a worldwide communications network. In this manner, information is relayed to weather forecast centers around the globe. Radiosonde observations usually are taken twice daily at 0000 hours (midnight) and 1200 hours (noon) Greenwich mean time.

Special tracking equipment monitors the movement of the radiosonde, which is converted into wind speed and wind direction data. When the balloon bursts, the radiosonde falls back to Earth by parachute. Related category;
