English Dictionary

radiosonde

noun

A miniature radio carried aloft (e.g. by an uncrewed balloon, an airdrop from a crewed aircraft, or a sounding rocket) to automatically transmit measurements of the upper air such as the wind speed, pressure, temperature, and relative humidity to a receiving station on the ground.

The radiosonde measures various atmospheric parameters such as temperature, humidity, and pressure.

意味（1）

A miniature radio carried aloft (e.g. by an uncrewed balloon, an airdrop from a crewed aircraft, or a sounding rocket) to automatically transmit measurements of the upper air such as the wind speed, pressure, temperature, and relative humidity to a receiving station on the ground.

The ultimate limitation of radiosonde networks is the impracticality of global deployment. […] Although, in principle, satellite soundings should be able to match radiosonde accuracies, in practice, they have errors of at least twice those of radiosondes.
