A radiosonde (sonde is French and German for probe) is a battery-powered telemetry instrument package carried into the atmosphere usually by a weather balloon that measures various atmospheric parameters and transmits them by radio to a ground receiver. Radiosondes are an essential source of meteorological data, and hundreds are launched all over the world daily. In this talk I will discuss a brief history of radiosondes, different types of sondes, what sondes measure and how, where soundings are taken, and how the data collected by radiosondes are used.
