3D Water Vapor Signature of Tropical Storms: GNSS Tomography of the 10 Most Severe Rainfall Events in Hong Kong 2015–2025

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Monitoring water vapor during extreme events is crucial for understanding atmospheric physics, as well as for improving the prediction of severe weather and enhancing early warning systems. The major gap in monitoring water vapor during extreme events lies in the limited spatial and temporal resolutions of existing techniques.

Anomalous Zenith Total Delays for an Insular Tropical Location: The Tahiti Island Case

Remote Sensing, 2022
The weighted mean temperature of the troposphere, Tm, is a key parameter in GNSS meteorology. It can be routinely derived based on meteorological data from radiosonde (RS) or numerical weather models. Alternatively, it can be also derived through a least-

Enhancing winter canola integration into soybean cropping systems through relay intercropping

Agronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Winter canola (Brassica napus L.) has the potential to enhance the sustainability of soybean‑based cropping systems when integrated as a relay‑intercropped winter oilseed. A critical factor for successful overwinter survival is timely seeding that allows sufficient rosette development before dormancy.

MSWD: A Hybrid Machine‐Learning Framework for Slant Wet Delay Modeling

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Space geodetic techniques such as Global Navigation Satellite Systems (GNSS) and Very Long Baseline Interferometry (VLBI) are limited by direction‐dependent tropospheric delays, with slant wet delay (SWD) being the most variable component and a major error source.

Precipitable Water Vapour Estimation from GNSS Observations: Methodology and Evaluation during a High-Precipitation Month in Santa Maria (RS) [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Precipitable Water Vapour (PWV) represents the total amount of water vapour contained in a vertical column of the atmosphere that is available for precipitation.

GNSS Zenith Wet Delay as a Boundary Layer Diagnostic: Regime‐Dependent Turbulence Signatures From Large Eddy Simulation and Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Global Navigation Satellite Systems (GNSS) provide continuous measurements of zenith wet delay (ZWD), reflecting column‐integrated atmospheric water vapor. While the slowly varying ZWD is routinely assimilated in numerical weather prediction, the rapid fluctuations on timescales of seconds to minutes that arise from boundary‐layer turbulence ...

Empirical model for mean temperature and assessment of precipitable water vapor derived from GPS

Geodesy and Geodynamics, 2013
The estimation of Precipitable Water Vapor (PWV) derived from Global Positioning System (GPS) data at the IGS site WUHN is assessed by comparing with PWV obtained from radiosonde data (No.57494) in Wuhan.

Using Landsat Satellite Imagery to Investigate Spatial and Temporal Variation in Life History Traits in a Long‐Term Study Population of Superb Fairy‐Wrens Malurus cyaneus

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We used 27 years of data from an insectivorous passerine in southeastern Australia, the superb fairy‐wren Malurus cyaneus, to assess how climate variation influences vegetation productivity and, indirectly, reproduction and survival via potential trophic interactions.

Simulated Impacts of the 2023 Megadrought on Black Spruce Potential Productivity Across Canada

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Black spruce (Picea mariana) is a dominant tree species across the Canadian boreal forest and a key contributor to national carbon dynamics. However, its growth and stand productivity are increasingly threatened by intensifying droughts, rising temperatures, and associated disturbances such as wildfire. In this study, we used the process‐based

Reinvestigating the Nightside Ionosphere of Mars With 8 Years of Mars Express and MAVEN Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Tailward ion escape in the nightside magnetotail is one of the dominant paths of ion escape from Mars. The Martian nightside ionosphere can serve as a major reservoir for this escape channel, but its global distributions and dependence on the upstream solar wind have not been fully investigated due to observational limitations.
