Space Weather, Volume 24, Issue 3, March 2026.Abstract The sporadic E (Es) layer, a key manifestation of ionosphere‐neutral atmosphere coupling, is highly sensitive to geomagnetic storms. Using more than 25,000 daily radio occultation profiles from the Tianmu‐1 and COSMIC‐2 constellations, this study investigates the global response of the Es layer to the May 2024 storm.

Estimating Zenith Tropospheric Delay Based on GPT2w Model
IEEE Access, 2019 To precisely and conveniently estimate zenith tropospheric delay (ZTD), troposphere refractivity is deduced through global pressure and temperature 2w (GPT2w) model and surface meteorology devices, ZTD is estimated based on integration of refractivity in

Can Android Smartphones Contribute to GNSS Meteorology?
The Global Navigation Satellite System (GNSS) is an essential tool for tropospheric monitoring. Currently, GNSS meteorology relies mainly on the data collected from geodetic-grade receivers of global or regional networks. However, such stations are costly, and thus cannot be densely deployed, especially in less developed regions.

GNSS meteorology in Egypt: Modeling weighted mean temperature from radiosonde data
Alexandria Engineering Journal, 2019 This study uses 3600 radiosonde profiles obtained by experimentation from four stations situated in Egypt within 2015–2016 period and Bevis linear regression method was applied to develop a new water vapor weighted temperature (Tm).Bevis, Schueler, Yao, Liou, Suresh Raju and Wayan models performances are assessed using the Tm estimated in this study ...

Comparison of GPS slant wet delays acquired by different techniques [PDF]
, 2012 This paper discusses the quality of slant wet delays (SWD) computed from GPS measurements. The SWDs are generally used as input data for GPS tomography, which allows the three-dimensional reconstruction of water vapour distribution in the atmosphere ...

Deep Earthquakes Can Generate Larger Co‐Seismic Displacements Than Shallow Events
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract We report the counter‐intuitive observation that a deep earthquake can generate larger co‐seismic displacements than a shallow event across a broad region (e.g., >4° from epicenter). This finding is based on a detailed comparative GNSS analysis of the co‐seismic displacement observations from two MW 8.3 events—the 2013 598.1 km‐deep Okhotsk ...

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract The gradient drift instability (GDI) commonly occurs in the high‐latitude ionosphere and is widely recognized for producing elongated striation structures. While previous studies have established the linear growth and primary nonlinear development of striations, the formation of secondary structures remains not fully understood.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract The Laguna del Maule volcanic field in Chile has been uplifting at exceptional rates since 2007, offering a unique opportunity to examine the interplay between crustal deformation and magma dynamics. To understand this relationship, we integrate GNSS with local seismic observations from 2013 to 2024 to model the reservoir strain field ...
