Analysis of Radiosonde Daily Bias by Comparing Precipitable Water Vapor Obtained from Global Positioning System and Radiosonde [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2010
In this study, we compared the precipitable water vapor (PWV) data derived from the radiosonde observation data at Sokcho Observatory and the PWV data at Sokcho Global Positioning System (GPS) Observatory provided by Korea Astronomy and Space Science ...

The effect of data sources on calculating mean temperature and integrated water vapor in Iran

open access: yesMeteorological Applications, 2023
The weighted mean temperature (Tm) plays a crucial role in calculating Precipitable Water Vapor (PWV) and integrated water vapor (IWV) using Global Navigation Satellite Systems (GNSS) techniques.

A New Look at Radiosonde Data prior to 1958 [PDF]

open access: yesJournal of Climate, 2009
Abstract Historical radiosonde data are known to suffer from inhomogeneities. The first radiosonde intercomparison was made at Payerne, Switzerland, in 1954, and a major international effort to standardize the network, including launch times, was made for the International Geophysical Year (IGY) in 1957–58.

The Atmosphere Has Become Increasingly Unstable During 1979–2020 Over the Northern Hemisphere

open access: yesGeophysical Research Letters, 2023
Atmospheric instability affects the formation of convective storms, but how it has changed during recent decades is unknown. Here we analyze the occurrence frequency of stable and unstable atmospheric conditions over land using homogenized radiosonde ...

Statistical Analysis of Turbulence Characteristics over the Tropical Western Pacific Based on Radiosonde Data

open access: yesAtmosphere, 2020
The tropical region is a key area for the interaction between the stratosphere and troposphere. The strong convective activity in the troposphere produces a series of gravity wave activities, which result in strong and widespread turbulence over the ...
