Global Primary and Secondary Microseism Multi‐Decade Geographic Variation, Secular Intensification, and Period Lengthening

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Earth's long period background seismic wavefield is dominated by two distinct processes that couple ocean wave energy to a global microseism wavefield. We assess global microseism intensity in the secondary (4–10 s) and primary (14–20 s) bands, and across eight 2 s‐wide period bands between 4 and 20 s.

The Energy Exascale Earth System Model Version 3: 2. Overview of the Coupled System

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract The Energy Exascale Earth System Model version 3 (E3SMv3) represents the latest advancement in Earth system modeling developed by the U.S. Department of Energy (DOE). Building upon previous versions, E3SMv3 introduces significant updates across its coupled components to enhance capability and improve fidelity.

Using Terrestrial Organic Matter to Reconstruct the Stable Carbon Isotope Composition of the Atmosphere

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Carbon fluxes to Earth's atmosphere are reflected in the carbon isotope composition of atmospheric CO2 (δ13Catm). δ13Catm is used to track past changes to the global carbon cycle and is a variable in many paleoclimate proxies. However, existing δ13Catm proxy records derived from marine carbonates are relatively low‐resolution prior to the ...

Unraveling Super Equatorial Plasma Bubbles (EPBs) Evolution During the 23 April 2023 Storm: Multi‐Instrument Observations and GITM‐SAMI3 Simulation

open access: yesSpace Weather, Volume 24, Issue 4, April 2026.
Abstract Storm‐time equatorial plasma bubble (EPB) dynamics play a critical role in space weather impacts on communication and navigation systems, yet the mechanisms governing their formation and evolution under storm conditions remain poorly understood.
