Definition - What does Radiosonde mean?
Radiosonde is a battery-powered telemetry instrument that is used to measure atmospheric parameters. It consists of a weather balloon that transmits signals through a radio to a ground receiver. It generally operates at 404 MHz to 1690 MHz. It is useful because it acts as an essential source of collecting meteorological data.Over time, continuous advancements are taking place thus modern radiosonde can calculate altitude, temperature, relative humidity, wind, cosmic ray and geographical position.
Petropedia explains Radiosonde
A Radiosonde is attached with a weather balloon that either consists of hydrogen or helium. Due to the presence of the gas, it lifts the instrument at a height of approximately 115,000 feet. The main purpose is to make weather forecasts based on the analysis of meteorological maps. It represents the real-time measurements that help to close the gap between the predictions of models and the true measurements. Moreover, it provides details about various atmospheric changes that include pressure, temperature and humidity.
