A miniature radio carried aloft by an unmanned balloon to broadcast the pressure, temperature, and relative humidity of the upper air and to automatically transmit that information to the ground.
A radiosonde is a unit for use in things such as weather balloons that measures various atmospheric parameters and transmits them to a fixed receiver. Radiosondes may operate at a radio frequency of 403 MHz or 1680 MHz and both types may be adjusted slightly higher or lower as required. A rawinsonde is a radiosonde that is designed to only measure wind speed and direction. Colloquially, rawinsondes are usually referred to as radiosondes. Modern radiosondes measure or calculate the following variables: ⁕Pressure ⁕Altitude ⁕Geographical position ⁕Temperature ⁕Relative humidity ⁕Wind ⁕Cosmic ray readings at high altitude Radiosondes measuring ozone concentration are known as ozonesondes.
