Chorus Wave‐Induced Ionospheric Variability

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Electron microbursts are short‐lived but intense electron precipitation and constitute a significant source of electron losses into the ionosphere and lower atmosphere. They are primarily produced by wave‐particle interaction with chorus waves in the magnetosphere.

Mapping Glacier Bed Topography in Crevassed Regions: A New Passive Seismic Reflection Method Applied to Isunnguata Sermia, West Greenland

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Glacier bed topography is crucial for modeling ice mass loss. However, heavily crevassed regions are challenging to survey using conventional methods, leading to data gaps. We establish a passive seismic approach exploiting naturally occurring crevassing events recorded with a dense seismic array to image the ice–bed interface without spatial ...

Excessive Convective Precipitation Formation Caused by Warm‐Phase Bulk Microphysical Scheme Biases: A Multi‐Platform Observational Diagnosis

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract Recent work has demonstrated that convection‐permitting models often produce a greater number of precipitating convective cells compared to radar observations. Congestus‐depth cells contribute most to the bias, which are colloquially termed “popcorn convection.” This study explores warm‐phase microphysical contributions to the bias using ...

MAIAC Aerosol Algorithm Over Water

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract MAIAC VIIRS Collection 2 aerosol product for the first time provides global coverage over land and ocean. This paper gives a first systematic description of MAIAC ocean aerosol algorithm covering cases of open ocean, waters with sediments and brown waters from rivers' discharge.

Numerical Simulations of 3D Scattering Structures Reveal Systematic Underestimation of Marsquake Magnitudes

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Determining marsquake magnitudes is essential for assessing seismic activity on Mars, yet previous estimates neglect three‐dimensional (3D) scattering effects. The exceptionally long‐lasting coda of the largest recorded marsquake, S1222a, provides a unique opportunity to quantify how crustal heterogeneities affect waveform propagation and ...
