Near real-time water vapor tomography using ground-based GPS and meteorological data: long-term experiment in Hong Kong [PDF]

open access: yesAnnales 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]

open access: yes, 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]

open access: yesGeodetski 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 ...

Optimizing Boundary Conditions in GNSS Tomography: A Continuous 7‐Month Case Study in the Amazon

open access: yesGeophysical Research Letters, 2023
Different estimates of the regional water vapor scale height, taken from ERA5 reanalysis, in situ observations and the direct optimization of retrieved water vapor profiles in GNSS tomography, are found to have major impact in the performance of ...

Kinematic ZTD Estimation from Train-Borne Single-Frequency GNSS: Validation and Assimilation

open access: yesRemote Sensing, 2021
Water vapour is one of the most important parameters utilized for the description of state and evolution of the Earth’s atmosphere. It is the most effective greenhouse gas and shows high variability, both in space and time.

GNSS Meteorology and Tropospheric Paramteres Investigation

open access: yesGeodetski 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. Scientists have found a way to use systematic influence that troposphere has on GNSS signal and turn it ...
