Response of Radiosonde Thermistors
Review of Scientific Instruments, 1957The lag coefficient of a thermometer of cylindrical shape is shown to be approximately proportional to the one-half power of its diameter and inversely proportional to the one-half power of the product of ventilation speed and density of the environmental air.

The radiosonde: The stratosphere laboratory
Journal of the Franklin Institute, 1941Abstract The radiosonde, the most recently developed tool for use in the investigation of phenomena in the upper atmosphere, is described. The various merits and disadvantages of the three systems now in use for the transmission of physical data from the stratosphere are reviewed.In a discussion of present-day radiosonde technique are included ...

The Reference Radiosonde as a Tool for Improving Meteorological Data from Conventional Radiosondes
IEEE Transactions on Geoscience Electronics, 1973The Weather Service of the Federal Republic of Germany, along with several other national services, has responded to an international call for development of reference radiosondes. Such devices make use of sensing methods with a high degree of precision which are superior to any conventional upper-air sensing system.

An Improved Fully Electric Radiosonde *
Bulletin of the American Meteorological Society, 1950A fully electric radiosonde using the Finnish principle is described. The temperature is measured with a temperature sensitive dielectric; the humidity by the determination of the psychrometric difference; and the pressure by a corrugated diaphragm which positions a cylindrical condenser.

Thin-Wire Thermometer for Radiosondes
Review of Scientific Instruments, 1954It is shown that the thinner the thermometer element of a sounding balloon, the smaller the errors due to radiations from the sun and the earth. Such a thin wire thermometer made from white gold wire as described herein, was delivered March 20, 1941, to the U. S. Weather Bureau. The instrument sends off its findings by radio signals in Morse code.
