Reproducibility of VIZ Radiosonde Data and Some Sources of Error

Journal of Applied Meteorology, 1981
Abstract The reproducibility of VIZ radiosonde data has been investigated using three ascents with two sondes on the same balloon. Provided the baseline check is carried out carefully and under favorable conditions, the reproducibility of the VIZ sonde is quite satisfactory with the deviations well within the accuracies specified by the manufacturer ...

Hemispheric Investigation of Warm Rain by Radiosonde Data

Journal of Applied Meteorology, 1963
Abstract Warm rains at 62 stations in the northern hemisphere for a period of one year were examined geographically, seasonally and from other points of view by radiosonde data. The examination disclosed that warm rain fell more frequently than expected.

Analysis of radiosonde data on tropospheric water vapour in Nigeria

Nigerian Journal of Physics, 2009
The analyses of some atmospheric water vapour parameters derived from radiosonde data at the three existing radiosonde stations in Nigeria are reported. The stations essentially represent the climates of the southern (coastal), middlebelt (savannah), and northern (sub-sahel) regions of thecountry.

Moisture Analysis from Radiosonde and Microwave Spectrometer Data

Journal of Applied Meteorology, 1981
A method for analysis of the horizontal and vertical distributions of the moisture field utilizing satellite, upper air and surface data is proposed in this paper. A brief overview of the microwave sensors on board Nimbus 5 and 6 is also presented. A technique is provided utilizing the radiosonde data sets to calibrate the satellite field of total ...

Using radiosonde data to determine statistical properties of convection

2003
The outflow from deep convection influences the budgets of water vapor and other trace constituents in the upper troposphere, and may lead to ozone depletion and long term climate change as a result of radiative cooling. However, the processes that control the altitude of convective outflow are poorly understood at present.

Reanalysis without Radiosondes Using Ensemble Data Assimilation

Monthly Weather Review, 2004
Abstract Studies using idealized ensemble data assimilation systems have shown that flow-dependent background-error covariances are most beneficial when the observing network is sparse. The computational cost of recently proposed ensemble data assimilation algorithms is directly proportional to the number of observations being assimilated.

Fusion of Radiosonde and GPS Data for Water Vapor Tomography

2019
The technique of ground-based GPS tomography is a newly spatial tool to sense the water vapor profile in atmosphere area. It has become a complementary technique for other conventional atmospheric sounding techniques. In this study, the radiosonde data was utilized to improve the accuracy of GPS tomography by forming the vertical constraint information.

Radiosonde Data for Characterization of a Mountain Environment in British Columbia

Ecology, 1969
Thermograph records of the frequency of freezing and sub—freezing temperatures at altitudes of 3,200 ft (975 m) and 4,000 ft (1,219 m) on a mountain slope were compared with published radiosonde data of the same parameter from the same altitudes in the atmosphere.

An investigation of solar activity effects in Australian radiosonde data

Journal of Atmospheric and Terrestrial Physics, 1994
Abstract Radiosonde data spanning 25 yr have been subjected to superposed epoch analysis using as key days those days with major solar flares. A clear decrease in atmospheric temperature is observed three days after the key day at Alice Springs. Monte Carlo tests and the Sign Test confirm the significance of this result.
