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.

Contrasting the TEMPO and TROPOMI Views of Tropospheric NO2: Implications for Diurnal Variability and Model Evaluation

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Nitrogen dioxide (NO2) is a key indicator of unhealthy air, yet its sub‐daily spatiotemporal variability has not been widely characterized across large spatial scales in North America. Tropospheric Emissions: Monitoring of Pollution (TEMPO), a geostationary hyperspectral UV‐Vis instrument, offers up to 12 hourly observations per location ...

Enhanced Enantioselective Optical Trapping Enabled by Longitudinal Mie Resonances in Silicon Nanodisks

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Longitudinal Mie resonances in silicon nanodisks, excited by an azimuthally–radially polarized beam, generate strong optical chirality gradients with minimal achiral background. Magnetic quadrupole modes enable selective enantiomer trapping, achieving predicted selectivities over 100 for |κ|≥0.03 $\vert \kappa \vert \ge 0.03$ and robust performance ...

Marine Aerosol to Refinery Emissions: Transport and Evolution of CCN in the Houston Metropolitan Area and Their Impact on Cloud Formation

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The Experiment of Sea Breeze Convection, Aerosols, Precipitation and Environment (ESCAPE) campaign aimed to untangle the impacts of contrasting aerosol sources on cloud microphysical properties within deep convective cells using airborne observations with the National Research Council Canada (NRC) Convair CV‐580 research aircraft.
