Evaluating Fire Indices for Fire Ignition and Spread Rate in the Western United States

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Wildfires are complex events that are challenging to model. Researchers and land managers often rely on fire indices as a proxy of fire risk in operational forecasts and future projections. However, in the scientific literature, the choice of which fire index to use is often arbitrary and not tied to specific fire behaviors. Here, we provide a

Climatology of Storm Characteristics for Sub‐Daily Heavy Precipitation in the Greater Alpine Region

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Characterizing storms that generate heavy precipitation across different timescales is essential for parameterizing and assessing stochastic weather generators, evaluating climate models, enhancing risk management, and understanding climate change impacts.

Localization and Classification of Gravity Wave Events From VIIRS Day/Night Band Satellite Imagery Using Machine Learning Techniques

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Gravity waves in the upper mesosphere produce diverse spatial patterns in nighttime airglow, but their global morphology has been difficult to characterize because manual identification is impractical for the massive satellite image archive. We developed a machine learning framework to detect and classify gravity wave events in imagery from ...

Democratizing Hydroclimate Science for Just and Resilient Futures

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Hydroclimatic extremes are intensifying, escalating risks to ecosystems, infrastructure, and vulnerable communities. Rapid technological innovation and scientific discovery offer powerful tools to address these challenges, yet a gap remains between hydroclimate knowledge production and its use in decision‐making.

Green Emissions From Sprite Tops

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Although sprite discharges above thunderstorms have been studied for about 35 years, science enthusiasts reported the existence of long‐duration green light emissions from sprite tops only recently using commercial digital cameras and named these events green ghosts.

Sensitivity of Bounce‐Averaged Diffusion Coefficients to the Latitudinal Variability of Lightning Generated Whistlers

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The development of statistical wave models that include the underlying variability of the wave distributions is an important next step toward more accurate radiation belt models. Lightning‐generated whistlers (LGW) are an important wave mode in the plasmasphere; previous time‐averaged diffusion coefficients have used assumptions about the wave
