Assimilation of 5G Base Station Networks as Ultra‐Dense Atmospheric Sensors for Advancing Heavy Rainfall Prediction

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The zenith total delay (ZTD) retrieved from 5G communication base stations represents a novel observation source for numerical weather prediction (NWP), leveraging the extensive global deployment of 5G infrastructure. In this study, the direct assimilation of 5G‐ZTD observations into a high‐resolution NWP system was accomplished for the first ...

Correcting Unwrapping Errors Toward Reliable Rock Glacier Velocity From InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Rock Glacier Velocity is an Essential Climate Variable Permafrost Quantity, providing a quantifiable indicator of mountain permafrost evolution. Despite its wide usage, multi‐temporal InSAR often substantially underestimates rock glacier velocities compared to ground‐based measurements, limiting its reliability.

Long‐Term Increase in Equatorial Rayleigh‐Taylor Instability: Synergistic Effects of Greenhouse Gas Cooling and Geomagnetic Field Secular Variation

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Equatorial plasma bubbles (EPBs) are ionospheric irregularities generated by Rayleigh–Taylor instability (RTI) that disrupt satellite communications. We quantify secular change of RTI growth rates and isolate underlying drivers using WACCM‐X simulations.

Extreme Atmospheric Moistening and Drying Events at Ny‐Ålesund and Their Relation to Weather Systems

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Understanding the role of water vapor in Arctic amplification requires a detailed evaluation of its spatio‐temporal variability. In this work, we use an integrated water vapor (IWV) data set from a ground‐based microwave radiometer at Ny‐Ålesund, Svalbard, covering 2012–2024, to characterize temporal IWV variability.
