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 may operate at a radio frequency of 403 MHz or 1680 MHz. A radiosonde whose positio...
