Weather balloon
A weather or sounding balloon is a balloon which carries instruments aloft to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde. To obtain wind data, they can be tracked by radar, radio direction finding, or navigation systems . Balloons meant to stay at a constant altitude for long periods of time are known as transosondes.The above text is a snippet from Wikipedia: Weather balloon
