A Multiband Optical‐Radio View of Lightning Return Strokes Exposes Divergent 337/777 nm Emission Dynamics

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Simultaneous observations of ultraviolet (337 nm) and near‐infrared (777 nm) lightning emissions provide insight into streamer and leader processes. However, coordinated ground‐based measurements of these bands during return strokes remain scarce.

Wilson's Atmospheric Electron Accelerator: A Centennial Perspective

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract As of the time of writing this letter, we mark the centennial of Wilson's runaway electrons proposed in 1925. Owing to instrumentation limitations, Wilson and his students could not detect the particles anticipated by theory Chilingarian et al. (2025, https://doi.org/10.1029/2024jd042350).

Quantifying the Rapid Propagation of Rainfall and Evapotranspiration Signals Into Soils

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Precipitation and evapotranspiration are major drivers of soil moisture dynamics, which in turn influence plant water availability, biogeochemical reactions, and trace gas emissions. However, it has been unclear whether evapotranspiration signals propagate through soil columns differently than precipitation signals do.

Imaging of Biphoton States: Fundamentals and Applications

Advanced Functional Materials, Volume 36, Issue 40, 18 May 2026.
Quantum states of two photons exhibit a rich polarization and spatial structure, which provides a fundamental resource of strongly correlated and entangled states. This review analyzes the physics of these intriguing properties and explores the various techniques and technologies available to measure them, including the state of the art of their ...
