Long‐Term High‐Resolution Radiosonde Measurements Reveal More Intensified and Frequent Turbulence at Cruising Altitude in China

Geophysical Research Letters
Turbulence is of great importance for aviation safety, but its long‐term trend in China remains unclear due to the scarcity of in‐situ measurements. Here the national‐scale assessment of turbulence dissipation rate (ε) at flight cruising altitude (200 ...

Development of a cloud particle sensor for radiosonde sounding

, 2016
. A meteorological balloon-borne cloud sensor called the cloud particle sensor (CPS) has been developed. The CPS is equipped with a diode laser at  ∼  790 nm and two photodetectors, with a polarization plate in front of one of the detectors, to count the

Unconstrained GNSS Water Vapor Tomography With Real Data and LEO Augmentation

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The availability of four complete GNSS constellations (GPS, GLONASS, BeiDou and Galileo) offers, for the first time, the possibility of performing water vapor tomographic inversions that do not rely on external data. A tomographic model that includes no external constraints and requires no first guess and no virtual observations is described ...

Validation of brightness and physical temperature from two scanningmicrowave radiometers in the 60 GHz O 2 band using radiosonde measurements

, 2016
. In this paper, we address the assessment of the tropospheric performance of a new temperature radiometer (TEMPERA) at 60 GHz. With this goal, an intercomparison campaign was carried out at the aerological station of MeteoSwiss in Payerne (Switzerland).

Satellite/radiosonde comparison

, 1988
Collocated measurements of radiosonde and TIROS Operational Vertical Sounder (TOVS) data are compared to determine whether significant latitudinal, seasonal, or instrumental biases exist.

Radiosonde intercomparison

, 1988
The largest amount of material ever collected from a radiosonde comparison was examined. Radiosondes from Australia, Finland, India, and the United States were involved. Data were received from 100 soundings, each of which was a simultaneous in situ test

Use of GPS and radiosonde data for estimating water vapour attenuation on satellite-earth links [PDF]

, 2004
Water vapour is one of the critical components of the earth's atmosphere. It has a significant attenuation effect at millimeter wavelength [I], as well as plying a key role in the global climate system [2].
