A radiosonde radiometer

pure and applied geophysics, 1966
An inexpensive and simple form of radiometer capable of attachment to the American Bureau of Standards type radiosonde is described: it measures the upward flux of longwave radiation when used on night ascents. A slight modification to the telemetry circuit of the standard radiosonde enables the radiation signals to be obtained in addition to the usual

The Ubiquitous Radiosonde

Weatherwise, 2013
The radiosonde, a meteorological instrument that is carried aloft by weather balloons to transmit data on atmospheric conditions, represents the fusion of man's ingenuity and inquisitiveness about ...

The “Chirp” Digital Radiosonde

Journal of Applied Meteorology, 1967
Abstract This paper reports on a digital measurement (“chirp”) system which has application for a wide range of meteorological and earth satellite measurements. The system employs a simple concept in which a voltage pulse, proportional to a sensor voltage, is used to generate a burst of pulses from a voltage controlled oscillator (VCO).

Radiosonde Temperature-Baseline Inaccuracy

Journal of Applied Meteorology, 1968
Abstract An analysis of tropical radiosonde temperature measurements made during the Line Island Experiment suggests that conventional radiosonde preflight procedures are inadequate in a remote tropical environment. Temperatures computed from conventional and modified baseline techniques are compared at five pressure surfaces, 1000, 800, 600, 400 and ...

Position measurements with radiosondes

IEEE Journal of Oceanic Engineering, 1989
The use of Omega sondes, designed for the determination of upper air wind vectors, for relative position measurements on the ground is described. The technique shows promise in measuring the deformation of sea ice, the motion of oceanic surface water, and the trajectories of constant-level balloons.

Range-adjusting radiosonde recorder

Electrical Engineering, 1949
A RADIOSONDE is the air-borne unit of an air-to-ground telemetering system. This equipment transmits audio frequencies in time sequence, which represent temperature and humidity, and a fixed reference signal, covering a range from 8 to about 200 cycles per second.

Response of Radiosonde Thermistors

Review of Scientific Instruments, 1957
The 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, 1941
Abstract 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, 1973
The 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, 1950
A 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.
