Crossword clues for radiosonde
radiosonde
Wiktionary
n. A miniature radio carried aloft by an unmanned balloon 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.
Wikipedia
A radiosonde 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. Modern radiosondes measure or calculate the following variables: altitude, pressure, temperature, relative humidity, wind (both wind speed and wind direction), cosmic ray readings at high altitude and geographical position ( Latitude/ Longitude). Radiosondes measuring ozone concentration are known as ozonesondes.
Radiosondes may operate at a radio frequency of 403 MHz or 1680 MHz. A radiosonde whose position is tracked as it ascends to give wind speed and direction information is called a rawinsonde ("radar wind -sonde"). Most radiosondes have radar reflectors and are technically rawinsondes. 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.

A new map, a cartology of Geiger counters, seismographs, radiosondes and gauges.
One evening, as he watched the Sun already sunk throw its rays around the edge of the western earth to illuminate one of his radiosondes rising into the highest layers of the atmosphere, a hundred miles up, making it shine while Earth grew increasingly dark, he realized that with imperceptible steps he was making the transition from engineer to scientist, for with the skills of the former he was attacking the mysteries which preoccupied the latter, and he was increasingly proud to stand in both camps, a man who could at the same time control material things like metals and wind tunnels yet grapple with the ultimate mysteries such as life at incredible altitudes.
Many items were carried as standard equipment in ICY parties, both in the field and at base camps, and none more standard than the magnesium flares which first came into common use in the Antarctic over a quarter of a century ago - they are indispensable as location beacons in the long polar nights - and radiosondes.
