radiosonde observation

radiosonde observation

[′rād·ē·ō‚sänd ‚äb·zər‚vā·shən]
(meteorology)
An evaluation in terms of temperature, relative humidity, and pressure aloft, of radio signals received from a balloon-borne radiosonde; the height of each mandatory and significant pressure level of the observation is computed from these data. Also known as raob.
