Lake Morphometry Influences the Accuracy of SWOT Estimates of Water Level

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Lake water surface elevation (WSE) data in Sweden are needed to understand water supply and ecosystem services provision. SWOT can complement WSE in situ measurements, but the influence of lake shape on its accuracy remains unclear. We explore the performance of the SWOT pixel‐cloud and this influence across 62 lakes from August 2023 to ...

Drivers of Trends in Northern Hemisphere Cold Spell Characteristics Over 1980–2025

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract This study quantifies trends in winter cold spell (CS) frequency, intensity, persistence and spatial extent across the Northern Hemisphere (NH) over 1980–2025. Cold spells are identified using a tracking methodology applied to daily near‐surface temperature anomalies from reanalysis.

Magma Pathways Beneath the Klyuchevskoy Volcanic Group, Kamchatka, Revealed by a Machine‐Learning‐Based Earthquake Catalog

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Klyuchevskoy Volcanic Group (KVG) is one of the world's largest clusters of subduction‐zone volcanoes and hosts a complex trans‐crustal magmatic system. Using a machine‐learning–based detection workflow applied to data from the KISS seismic experiment in 2015–2016, we obtained an enhanced earthquake catalog for KVG volcano‐magmatic activity ...

A Reconciled Satellite Record Reveals a Negative Low Cloud Feedback Over the Past 47 Years

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Low‐cloud feedback continues to dominate uncertainty in climate sensitivity, with no direct observational estimate to date. Here we provide the first such estimate by combining satellite and reanalysis data sets within a cloud‐controlling factor (CCF) framework.

Nickel‐Free Synthesis of Poly(pyrene‐4,5,9,10‐tetraone) for Sodium‐based Batteries: Insights into Electrode Architecture and Reversible Na‐ion Insertion

Advanced Energy Materials, Volume 16, Issue 28, 22 July 2026.
A nickel‐free and practical synthesis strategy to poly(pyrene tetraone) and its integration with a percolated CNTs/Ketjen Black network enables stable cycling and efficient energy storage in a sodium‐based batteries. This work demonstrates how controlling polymer structure and electrode architecture improves ion transport and mitigates dissolution in ...
