Toward a Dynamic Model for Topside Ionospheric Irregularities: Spherical Harmonic Decomposition

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Ionospheric irregularities arise from highly dynamic and turbulent processes related to magnetosphere‐ionosphere coupling and can lead to electromagnetic signal distortion or loss of lock events in global navigation satellite system signals, representing a hazard associated with space weather events. For this reason, understanding and modeling

Quantifying the Impacts of the May 2024 Geomagnetic Storm on Transatlantic Aviation: Rerouting, Delays, and Economic Losses

Space Weather, Volume 24, Issue 3, March 2026.
Abstract The May 2024 geomagnetic storm, one of the most intense events of Solar Cycle 25 to date, caused widespread disruptions in aviation operations, particularly for polar and high‐latitude routes. This study quantifies the operational and economic impacts of the storm on 12 selected transatlantic flights between North America and Europe.

Global Bottomside Ionospheric Modeling Based on GNSS‐RO Observations From the Tianmu‐1 Constellation

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Radio occultation (RO) observations provide a crucial means for estimating the global Vertical Bottomside Electron Content (VBEC) in the ionosphere. However, the limited number of low Earth orbit (LEO) satellites in existing RO missions restricts the capability for high‐precision reconstruction of global VBEC spatiotemporal variations.

Quasi‐4‐Day Waves During the 2018/2019 SSW and Their Coupling to the Ionosphere Based on Whole Atmosphere Data Assimilation

Space Weather, Volume 24, Issue 3, March 2026.
Abstract A strong westward zonal wavenumber‐2 quasi‐4‐day wave (Q4DW) during the 2018/2019 Northern Hemisphere sudden stratospheric warming (SSW) is both captured by Aura Microwave Limb Sounder (MLS) observations and our new whole neutral atmosphere data assimilation system.

PPP‐RTK Atmospheric Correction Generation and Service Applicability: A Case Study During Typhoon Saola and Moderate Geomagnetic Disturbances in Hong Kong

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Complex space weather, such as typhoons and solar activity, can cause heavy rainfall and ionospheric disturbances, affecting the quality of Global Navigation Satellite System (GNSS) signals. Among GNSS positioning techniques, Precise Point Positioning Real‐time Kinematic (PPP‐RTK) uses atmospheric corrections and bias products to achieve fast ...

An enhanced pricing model for truck transportation: a case study in Swedish forestry

International Transactions in Operational Research, Volume 33, Issue 2, Page 775-797, March 2026.
Abstract Determining freight rates for heavy trucks involves a detailed analysis of multiple cost factors, including time, distance, fuel, and other operational costs, which collectively contribute to the overall compensation for transportation services. However, actual remuneration is based on more simplified agreements.

Formation of Secondary Structures Associated With the Gradient Drift Instability in the High‐Latitude Ionosphere

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.

Long Unrest (2007–2025) at Laguna del Maule: Linking Strain Field and Seismicity From GNSS and Seismic Data

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 ...
