Distinct Cloud‐to‐Ground Lightning Properties in Frontal Versus Warm‐Sector Heavy Rainfall Events
Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract Do systematic differences in cloud‐to‐ground (CG) lightning properties—particularly return stroke number and current intensity—exist across different thunderstorm types? This question is foundational not only to the atmospheric electricity but also to advancing lightning risk prediction, which crucially depends on a robust understanding of how

Increased Aerosols From Siberian Wildfires Buffered Arctic Warming During 2013–2019
Earth's Future, Volume 14, Issue 2, February 2026.Abstract During 2013–2019, global aerosols, influenced by regional clean air actions and wildfires, changed significantly. Clean air actions in China, Europe, and North America reduced anthropogenic aerosols, whereas Siberia experienced increased wildfire aerosols due to local warm and dry conditions.

Health Impact Analysis of Wildfire Smoke‐PM2.5 in Canada (2019–2023)
GeoHealth, Volume 10, Issue 2, February 2026.Abstract Wildfires are a source of air pollution, including PM2.5. Exposure to PM2.5 from wildfire smoke is associated with adverse health effects including premature death and respiratory morbidity. Air quality modeling was performed to quantify seasonal wildfire‐PM2.5 exposure across Canada for 2019–2023, and the annual acute and chronic health ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.Abstract Electron microbursts are among the most important loss mechanisms for energetic electrons in the Earth's radiation belts and are often driven by wave‐particle interactions with discrete chorus wave elements. Observations from the Balloon Array for Radiation‐belt Relativistic Electron Losses (BARREL) mission have revealed microburst events with

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.Abstract Whistler‐mode chorus waves play a key role in driving radiation belt dynamics by enabling both acceleration of electrons to relativistic energies as well as their loss into the atmosphere via pitch‐angle scattering. The ratio between the electron plasma frequency (fpe ${f}_{pe}$) and the electron gyrofrequency (fce ${f}_{ce}$) significantly ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.Abstract Terrestrial water storage (TWS) plays an important role in describing the Earth system, as water availability is decisive for ecosystems and human development. Since 2002, the Gravity Recovery and Climate Experiment (GRACE) and its Follow‐On (GRACE‐FO) mission have measured TWS anomalies with unprecedented accuracy, enabling a leap in ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.Abstract Lipids are powerful tools for reconstructing paleoenvironments and geologic processes because of their ubiquity and preservation in the rock record. Traditionally, organic geochemistry studies are targeted analyses of known biomarker compounds with known responses to past environmental conditions or geologic processes.

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.Abstract While data‐driven global weather models (e.g., GraphCast) excel at large‐scale circulation forecasts, they exhibit systematic biases in heavy precipitation prediction due to European Centre for Medium‐Range Weather Forecasts Reanalysis (ERA5) uncertainties and neural networks' tendency to over‐smooth rainfall fields.

Six‐Component Electromagnetic Wave Measurements of Sprite‐Associated Lightning
Radio Science, Volume 61, Issue 2, February 2026.Abstract Low frequency electromagnetic waves emitted by sprite‐producing lightning are normally measured using vertical electric fields or horizontal magnetic fields. Here we report for the first time the simultaneous measurement of electromagnetic waves from sprite‐producing lightning in all six electromagnetic field components Ex,Ey,Ez,Hx,Hy,andHz ...

Fire regime change in western Tasmania between 1830 and 2025
Geographical Research, Volume 64, Issue 1, February 2026.Sketches by N.J.B. Plomley of George Augustus Robinson western Tasmanian expeditions in 1830 and 1833, undertaken to persuade Aboriginal nations of western Van Diemen’s Land to leave their ancestral lands. Geographic analysis of Robinson journal of this remote area provides unique insights in the changes in fire regimes that followed this tragic ...
