Ionospheric Characterization Using VLF Whistlers

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Broadband very low frequency (VLF, 3–30 kHz) energy emitted from lightning travels long distances in subionospheric propagation modes. Some of this energy couples into the ionosphere and travels to satellite altitudes along a predominantly field‐aligned path in what is known as a “whistler” propagation mode. Along this path, these VLF signals (

Explainable Optimized LSTM Model for Sustainable Wind Power Forecasting in Smart Cities

International Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
Accurate wind‐power forecasting is essential for the successful integration of renewable energy into smart city grids. Traditional long short‐term memory (LSTM) networks face significant challenges in parameter optimization, leading to suboptimal forecasting performance.

Comparative Study of Upward Leader Inception During the Initial Stage of Negative and Positive Altitude‐Triggered Lightning

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Comparative analysis of positive and negative altitude‐triggered lightning striking a 30‐m tower beneath 35‐m floating wires reveals detailed bidirectional leader processes. It provides the first observational evidence of bidirectional leader behavior in positive altitude‐triggered lightning and highlights the connection process's driving ...

Study on Transient Overvoltage and Surge Arrester Electrical Stresses in Offshore Wind Farms Under Multiple Lightning Strokes

Journal of Marine Science and Engineering
Lightning strikes are a major cause of wind turbine (WT) damage, with approximately 80% of cloud-to-ground lightning strikes exhibiting a multi-stroke characteristic. Therefore, studying the transient overvoltages induced by multiple lightning strokes is

A Personal Voyage Among Earth and Space Physics Disciplines

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract I have organized my thoughts in an autobiographical way in relation to the several distinct phases of my career encompassing Earth and space physics. I discuss atmospheric and space physics topics of interest to me in an international context, and I emphasize the value of community activities and international conferences for the interchange ...

Oxychlorine Species on Mars: A Review

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

The communication of volcano information in New Zealand – a narrative review

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 591-608, December 2025.
ABSTRACT Communication of volcano information is critical for effective volcanic risk management. A variety of information is communicated to inform decisions and guide actions for planning, preparedness, and response. Such information needs to be reliable, and fit‐for‐purpose across different stages of volcanic activity (quiescence, unrest, short or ...

D‐Region Changes and Wave Activity Detected From Unusually Strong VLF Anomalies Associated With the January 2022 Tonga Volcanic Eruption

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract We present unusually strong daytime signal amplitude anomalies of 11.1 dB on JJI and 12.6 dB on VTX very low‐frequency (VLF) transmitter signals recorded at Suva, Fiji, due to the powerful Hunga Tonga–Hunga Ha'apai (HTHH) volcanic eruption (VE) on 15 January 2022 around 04:00 UT.
