The Wessex Convection Experiment (WesCon)–Observing the Evolving Structures of Turbulence (WOEST): Coordinated Aircraft and Ground‐Based Observations of Turbulence and Convection in Southwest England During Summer 2023

open access: yesGeoscience Data Journal, Volume 13, Issue 4, October 2026.
This paper summarises a coordinated field campaign in southern England in summer 2023 as part of the ParaChute programme, which studied atmospheric turbulence to improve weather and climate models. The field campaign used ground‐based instruments, aircraft and drones to observe turbulence and storms, creating datasets to develop better turbulence ...

Implementation of Ready-Made Hydrostatic Delay Products for Timely GPS Precipitable Water Vapor Retrieval Over Complex Topography: A Case Study in the Tibetan Plateau

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
For the timely retrieval of global positioning system based precipitable water vapor (GPS-PWV) over complex topography when there is no in situ pressure-derived zenith hydrostatic delays (ZHDs), this article evaluates three types of ready-made ZHD ...

Dynamic Evolution of a Storm‐Time “Super‐EPB” Event Over China on the Magnetically Disturbed Night of 01 December 2023

open access: yesSpace Weather, Volume 24, Issue 10, October 2026.
Abstract This paper investigates the dynamic evolution of a storm‐time “Super‐EPB” event over China on 1 December 2023 (Kp ≤ 7, SYM/H ≥ −130 nT) using multi‐instrument observations. Occurring near sunset as the IMF‐Bz abruptly turned southward, with auroral extension to midlatitudes, the “Super‐EPB” extended to 40°N with an apex height of ∼2,460 km ...

Assessment of the Impact of GNSS Processing Strategies on the Long-Term Parameters of 20 Years IWV Time Series

open access: yesRemote Sensing, 2018
Advanced processing of collected global navigation satellite systems (GNSS) observations allows for the estimation of zenith tropospheric delay (ZTD), which in turn can be converted to the integrated water vapour (IWV).

GNSS Meteorology for Disastrous Rainfalls in 2017–2019 Summer in SW Japan: A New Approach Utilizing Atmospheric Delay Gradients

open access: yesFrontiers in Earth Science, 2020
We studied disastrous heavy rainfall episodes in 2017–2019 summer in SW Japan, especially in the Kyushu region using tropospheric delay data from the Japanese dense global navigation satellite system (GNSS) network GEONET (GNSS Earth Observation Network).

Strategies for Mitigating the Impact of Ionospheric and Tropospheric Delay on Sentinel‐1 Interferograms in Northwestern Argentina

open access: yesEarth and Space Science, Volume 13, Issue 10, October 2026.
Abstract This study investigates the impact and mitigation of ionospheric and tropospheric delays on Sentinel‐1 interferograms in northwestern Argentina. The research focuses on the Santa María Basin in the south‐central Andes, a region characterized by moderate seismic deformation, monsoonal moisture supply, a steep east‐west rainfall gradient, and ...

Impacts of Neutral Wind‐Driven Currents on Geomagnetic Disturbances and Magnetospheric Dynamics During the May 2024 Storm

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The neutral wind dynamo generates ionospheric currents that can significantly affect high‐latitude electrodynamics during geomagnetic storms, yet its role in global magnetosphere‐ionosphere coupling is often underrepresented. We quantify the impact of wind‐driven currents on geomagnetic disturbances (GMDs) and magnetospheric dynamics during ...

Performance Evaluation of Blind Tropospheric Delay correction Models over Africa [PDF]

open access: yes, 2015
Tropospheric delay is a major error source in positioning by Global Navigation Satellite Systems (GNSS). Many techniques are available for tropospheric delay mitigation consisting of surface meteorological  models and global empirical models.

Simpler UNBabc Mapping Function for Global Positioning System (GPS) Tropospheric Delay [PDF]

open access: yes, 2010
The UNBabc(E) mapping function models should be simplified to allow faster calculation and also better understanding of the models. Many modern mapping function models use mapping functions in the form of continued fractions which is quite tedious in ...
