A Method to Improve the Distribution of Observations in GNSS Water Vapor Tomography
Sensors, 2018 Water vapor is an important driving factor in the related weather processes in the troposphere, and its temporal-spatial distribution and change are crucial to the formation of cloud and rainfall.

European GNSS troposphere monitoring for meteorological applications [PDF]
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Near real-time GNSS double-difference network processing is a traditional method still used within the EUMETNET EIG GNSS Water Vapour Programme (E-GVAP) for the atmosphere water vapour content monitoring in support of Numerical Weather Prediction. The standard production relies on estimating zenith tropospheric path delays (ZTDs)

Near real-time water vapor tomography using ground-based GPS and meteorological data: long-term experiment in Hong Kong [PDF]
Annales Geophysicae, 2014 Water vapor tomography is a promising technique for reconstructing the 4-D moisture field, which is important to the weather forecasting and nowcasting as well as to the numerical weather prediction. A near real-time 4-D water vapor tomographic system

Detection of Alpine Foehn in GNSS-ZWD time series: An innovative application of GNSS Meteorology [PDF]
, 2021 <p>The atmospheric delay experienced by a signal of the Global Navigation Satellite System (GNSS) is proportional to the water vapour content along the signal path. This fact is typically exploited in GNSS Meteorology by introducing GNSS derived atmospheric parameters like the Zenith Wet Delay (ZWD) in data assimilation schemes.

GNSS meteorology and tropospheric parameteres investigation [PDF]
Geodetski Glasnik, 2015 Troposphere plays crucial role for geodetic comunity, which can primarly be seen in its influence on GNSS observations. At the same time, troposhpere is the place where almost all hidrometeorological phenomena that effect our everyday life occure ...

Evaluation of E Layer Dominated Ionosphere Events Using COSMIC/FORMOSAT-3 and CHAMP Ionospheric Radio Occultation Data [PDF]
, 2020 At certain geographic locations, especially in the polar regions, the ionization of the ionospheric E layer can dominate over that of the F2 layer. The associated electron density profiles show their ionization maximum at E layer heights between 80 and ...
