Instrumental Artefacts Can Reverse Apparent Lightning–Climate Trends

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Lightning is an Essential Climate Variable, yet long‐term detection records may be compromised by changes in detection technology. Using more than three decades of Austrian lightning observations (1992–2024), we show that instrumental artefacts can reverse the apparent sign of lightning–climate trends.

Detection and Analysis of an Upward Jet‐Like Electrical Discharge Intercepting a High‐Altitude Research Aircraft

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract During a 2023 field campaign, a NASA ER‐2 research aircraft intercepted an upward jet‐like electrical discharge at 20 km altitude over an intense tropical thunderstorm. This event was analyzed using airborne multispectral optical sensors, electric field mills, X‐band radar, passive microwave, and ground‐based radio networks.

Diminished Radiative Cooling With Northward Wildfire Advance in the East Siberian Boreal Region

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Intensification of the Siberian wildfire regime is characterized by large increases in burned area above the Arctic Circle. Wildfire in boreal forests typically reduces albedo in the decades following fire, resulting in a net cooling effect. Here we quantified changes in albedo and the accompanying radiative forcing associated with a northward

Dependence of Neutralized Charge Amount on Meteorological Conditions in Summertime Lightning Discharges in Japan

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Lightning discharges in Gunma Prefecture, Japan, from June–September 2023 were analyzed to explore the dependence of the neutralized charge amount on cloud structures embedded in weather systems, mainly based on in situ measurements of the ground‐based electric field, radar and satellite remote sensing, and numerical simulations using a bulk ...

Design and Implementation of a Digitalised Marine Aids to Navigation Monitoring System for High‐Density Maritime Traffic Waters: A Case Study of the Strait of Malacca

Applied Research, Volume 5, Issue 5, October 2026.
A digitalised Aids‐to‐Navigation monitoring system (ARMS) was deployed across 478 installations in the Strait of Malacca and Malaysian waters, integrating multi‐sensor edge validation, hybrid AIS/VHF/cellular communication, and a centralised platform. It achieved 98.3% availability and cut fault‐detection time from weeks to just 8.4 min.
