Water vapor is a key variable in numerical weather prediction, as it plays an important role in
atmospheric processes. Nonetheless, the distribution of water vapor in the atmosphere is …

Water vapor tomography has been developed as a powerful tool to model spatial and
temporal distribution of atmospheric water vapor. Global navigation satellite systems (GNSS) …

Water vapour is a highly variable constituent of the troposphere; thus, its high-resolution
measurements are of great importance to weather prediction systems. The Global …

Abstract Precipitable Water Vapor (PWV) is a crucial parameter in climate research.
However, obtaining high precision PWV data remains a problem. Discrepancies in water …

Abstract Interferometric Synthetic Aperture Radar (InSAR) measurements are susceptible to
tropospheric delay induced by changes in tropospheric temperature, pressure, and water …

This article explores the enhancement of Global Navigation Satellite Systems (GNSS)
tropospheric tomography by integrating remote sensing data and employing various vertical …

The GNSS signal along its more than 20,000 km line of sight is bended, attenuated and
delayed. These effects are results of the Earth's atmosphere, and Sun radiation. Amongst all …
