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.
Special radiosonde:
1. rawinsonde: A radiosonde whose position is tracked as it ascends to give wind speed and direction information is called a rawinsonde ("radar wind -sonde").[1][2]
Most radiosondes have radar reflectors and are technically rawinsondes.
2. dropsonde: A radiosonde that is dropped from an airplane and falls, rather than
being carried by a balloon is called a dropsonde.
Radiosondes are an essential source of meteorological data, and hundreds are launched all over the world daily.
