Ionospheric Characterization Over Iran Using Multi‐Frequency IMB HF Transmitters and Global WSPRNET Reception During the 12 November 2025 Geomagnetic Storm

Space Weather, Volume 24, Issue 6, June 2026.
Abstract The Ionospheric Monitoring Beacon network in Iran provides continuous, multi‐frequency high‐frequency (HF) transmissions using WSPRNET modulation, enabling global reception and near–real‐time monitoring of ionospheric propagation conditions.

Hydrodynamic Characteristics of the Mainstem–Tributary Confluence in a Thermally Stratified Reservoir and the Effects of Selective Withdrawal

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Hydrodynamics characteristics in the mainstem–tributary confluence profoundly affect the local environment and ecology. Thermal stratification widely occurs in large reservoirs, and the need to investigate hydrodynamics of mainstem–tributary confluences is urgent. Moreover, selective withdrawal is often used to regulate the outflow temperature,

Subduction Parameters Controlling the Occurrence of Shallow and Deep Slow‐Slip Events (SSEs)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Slow‐slip events (SSEs) are transient aseismic fault‐slip phenomena that release tectonic stresses in a variety of tectonic environments, including subduction zones. In subduction margins, SSEs commonly occur along the plate interface at shallow (<20 km) and deep (30–60 km) depths.

Buoy Observations of Ocean Swell Propagation Across the Pacific Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract A network of more than 300 drifting wave buoys is used to study the propagation of ocean swell across the Pacific Ocean. Swell events are identified at buoys in the Equatorial region and then tracked along Great Circle propagation paths both forward and backward in time.

A Unified Vector Electromagnetic Framework for Ionospheric Scintillation and Polarization Effects in GNSS

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The ionosphere imposes coupled amplitude, phase, and polarization distortions on trans‐ionospheric Global Navigation Satellite System (GNSS) signals, reflecting the structure and dynamics of electron‐density irregularities. Classical weak‐scatter theory provides a mature framework for interpreting amplitude and phase scintillation, but these ...
