Finding Fireballs in Lightning: A Daily Pipeline to Find Meteors in Weather Satellite Data

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Weather satellite data contains a wealth of information well beyond its application to meteorology. The GOES weather satellite Geostationary Lightning Mapper instruments detect millions of lightning strikes per day. Within these “haystacks” of lightning are a handful of “needles” of bolides (aka bright fireballs, or exploding meteors). We have

SWOT Observations Constrain a 4D‐Var State Estimate of the California Current System

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission provides high‐resolution sea surface height (SSH) observations at 2‐km spacing, resolving submesoscale features typical of ageostrophic motions and associated with instabilities. Here, we demonstrate the assimilation of SWOT data into a regional configuration of the MITgcm for the ...

Impact of Magnetosphere Forcing and Model Resolution on Joule Heating Estimates in WACCM‐X During the 24 August 2005 Storm

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract We investigate the high‐latitude Joule heating in a recently developed high‐resolution configuration of the WACCM‐X whole‐atmosphere model coupled to the MAGE model. Model resolution and geomagnetic forcing effects during the severe (Kp>8) $(Kp > 8)$ geomagnetic storm on 24 August 2005 are analyzed, distinguishing storm peak and recovery ...

Distributed Acoustic Sensing (DAS) Waveforms: Effects of Source Signature, Geometry, and Attenuation

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Distributed acoustic sensing (DAS) records strain integrated over a finite gauge length depending on incidence angle, frequency, material velocities, fiber curvature, and gauge length. The DAS responses to a monofrequency plane wave of these are well understood.

The Complexity of Deep Aqueous Fluids in Planetary Ultramafic Mantles

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Planetary volatiles cycle through a planet's crust, mantle, and atmosphere, playing a crucial role in surface processes and habitability. Discussions of planetary volatiles traditionally focus on water, carbon, nitrogen, and sulfur, but fluids in contact with silicate rocks and ultramafic mantles can contain significant amounts of magnesium ...
