Global radiosonde balloon drift statistics [PDF]
Journal of Geophysical Research, 2011 [1] The drift of radiosonde balloons during their ascent has generally been considered a negligible factor in applications involving radiosonde observations. However, several applications envisioned for observations from the Global Climate Observing System (GCOS) Reference Upper Air Network (GRUAN) require estimates of balloon drift.

MTT-S International Microwave Symposium Digest, 2005
Two SAW stabilized oscillators with FM and PAM capability have recently been designed and breadboarded to provide 300 ppm frequency stability over a -70/spl deg/ C to +70/spl deg/C environment. The circuits are being developed for use in low cost, expendable radiosondes operating at 403 MHz and 1680 MHz.

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 “Chirp” Digital Radiosonde
Journal of Applied Meteorology, 1967Abstract 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, 1968Abstract 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, 1989The 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, 1949A 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.
