Analysis of Smoke Transport Over the Northeast US Caused by Wildfires in Canada During June 2023—Leveraging the HRRR‐Smoke Model Predictions and Remote Sensing Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The intensification of wildland fires across portions of Canada in early June 2023 led to significant smoke transport into the eastern United States, resulting in poor air quality and reduced visibility. Significant degradation of air quality was evident from PM2.5 surface measurements as the smoke plume moved southwards, which was confirmed ...

Analysis of the Charge Structure and Lightning Activity During a Severe Beijing Thunderstorm via an Innovative Balloon‐Borne 3D Electric Field Observation System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract We developed an innovative balloon‐borne observation system based on China's BeiDou sounding platform that integrates a three‐axis electric field sensor for in‐cloud measurements of thunderstorm electrification. On 13 May 2025, this system was deployed during a severe convective storm over Beijing. In combination with multisource observations,

Sprites Observed by ASIM: First Imaging Data Set and Temporal UV Emission Patterns

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract We present the first data set analysis of 41 imaging‐confirmed sprite events detected by the ASIM‐MMIA instrument. They were visible in the 337 nm camera images from an initial list of 102 candidates identified by the ultraviolet (UV 180–230 nm) photometer.

Ultra‐Low‐L Sub‐MeV Electron Microbursts During the May 2024 Super Storm

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract During the May 2024 super storm, we identified sub‐second microburst‐type relativistic electron precipitation events at McIlwain's L∼2 $L\sim 2$ in low‐Earth orbit using the Gamma‐ray Burst Monitor (CGBM) onboard the CALorimetric Electron Telescope on the International Space Station.

A Delayed Return Stroke Driven by Channel Charge Accumulation

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Based on combined VHF interferometer and fast/slow antenna measurements, we document an abnormal bolt‐from‐the‐blue lightning flash, which included two strokes. There are four successive attempted dart leaders following the first return stroke. The last detected downward leader stopped advancing at approximately 94 m and decayed.
