Beyond Geostrophic and Gradient Wind: Enhancing the Estimation of Climatic Wind Fields From Radio Occultation

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Wind approximations, such as geostrophic and gradient wind, are limited in their ability to accurately represent atmospheric conditions in the presence of significant planetary wave activity. Those approximations, while widely applied in synoptic‐scale wind field estimation, fail to capture the full complexity of atmospheric dynamics under ...

A Refined Regional Model for Estimating Pressure, Temperature, and Water Vapor Pressure for Geodetic Applications in China

Remote Sensing, 2020
Pressure, temperature, and water vapor pressure are basic meteorological parameters that are frequently required in Global Navigation Satellite System (GNSS) positioning/navigation and GNSS meteorology.

The use of products from ground-based GNSS observations in meteorological nowcasting [PDF]

Advances in Geosciences, 2010
Abstract. Convective rainfall is often focalized in areas of moisture convergence. A close relationship between precipitation and fast variations of vertically-integrated water vapour (IWV) has been found in numerous cases. Therefore, continuous monitoring of atmospheric humidity and its spatial distribution is crucial to the operational forecaster for

A Joint Inversion Algorithm of GNSS and InSAR for Continuous 3‐D Surface Velocities and Associated Horizontal Strain Rate Field

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Simultaneous analyses of complementary GNSS and InSAR measurements may lead to breakthroughs in our understanding of crustal deformation. We present an algorithm that combines InSAR with GNSS measurements, in which the GNSS data can be used either as original station velocities or as an interpolated and smoothed velocity field, to estimate ...

The Evolution of a Polar Cap Patch Into a Blob in the Nightside Ionosphere: Direct Observations of Multiple Blob Formation Mechanisms Acting Simultaneously on the Same Plasma

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract A polar cap patch was observed to exit the polar cap to become a blob as it entered the auroral oval on the nightside of the Earth under moderately quiet geomagnetic conditions (Kp = 3−). Auroral particle precipitation led to an increase in the electron density of the blob.

Improving Interpolating Accuracy of Weighted Mean Temperature by Using a Novel Lapse Rate Model in Compact VMF1 Product

Earth and Space Science
In GNSS (Global Navigation Satellite Systems) meteorology, the accuracy of precipitable water vapor (PWV) retrieved from the tropospheric delay of GNSS signals is affected by the conversion factor.

Use of Tropospheric Delay in GNSS-Based Climate Monitoring—A Review

Remote Sensing
The troposphere is a key component of the Earth’s climate system, modulating weather patterns and global temperatures through intricate interactions between water vapor, atmospheric pressure, and temperature.

Spatial Interpolation of GNSS Troposphere Wet Delay by a Newly Designed Artificial Neural Network Model

Applied Sciences, 2019
Global Navigation Satellite System (GNSS) signals arrive at the Earth in a nonlinear and slightly curved way due to the refraction effect caused by the troposphere. The troposphere delay of the GNSS signal consists of hydrostatic and wet parts.

Global GNSS Observation of Mesoscale Ionospheric Irregularities (2006–2024)

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Mesoscale ionospheric irregularities are statistically investigated using an unprecedented 19‐year long‐term global GNSS (Global Navigation Satellite System) TEC (total electron content) data set. These irregularities are represented by ionospheric fluctuations within a 5°× ${}^{\circ}\times $ 3.75° ${}^{\circ}$ (latitude by longitude) region ...
