Impact Craters Reveal a Deeper Rock‐Poor Regolith in the Lunar Highlands

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The only measurements of the highlands regolith occurred at the Apollo 14 and 16 landing sites, finding 10–15 m thick regolith; however, we show that the Apollo landing sites are anomalous due to their proximity to rare, highlands rocky craters and because they landed atop basin ejecta. Through observations of rocky crater populations, we show

Fault‐Controlled Plumbing System Beneath Lipari Volcanic Island Revealed by Seismic Matrix Imaging

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Lipari Island hosts an active magmatic–hydrothermal system, but its deep plumbing architecture remains poorly resolved due to strong seismic scattering. We apply passive seismic matrix imaging to public vertical‐component cross‐correlation functions from the dense 2018 Lipari nodal array, recovering relative‐reflectivity structures to ∼10 km ...

Detecting Irrigation From Spectral Differences Between Satellite and Modeled Soil Moisture Across the Contiguous United States

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Irrigation alters the terrestrial water cycle, yet its spatial distribution and temporal variability remain poorly constrained because existing data sets often rely on indirect proxies or inventories rather than observations tied to land‐surface water‐balance dynamics.

The Maintenance of the Longitudinal Subtropical Jet Structure During Austral Winter

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The austral winter subtropical jet maintenance is analyzed by comparing the observed upper tropospheric zonal momentum budget with an idealized aquaplanet model simulation with localized tropical heating in the summer hemisphere. The model and observations show great similarity, demonstrating the dominant role of localized tropical convection ...

Surface Expression of the Kuroshio Extension Northern Recirculation Gyre

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The Northern Recirculation Gyre (NRG) of the Kuroshio Extension (KE) has traditionally been viewed as subsurface‐intensified and difficult to identify at the sea surface. We combine a 2016–2025 subsurface mooring record, satellite altimetry, Argo trajectory‐based velocities, and historical near‐bottom velocities to reassess the sea‐surface ...

Satellite geodesy: Data acquisition

open access: yesEos, Transactions American Geophysical Union, 1971
After more than a decade of satellite observations, the data acquired during the past quadrennium have been the catalyst needed to bring about great achievements in satellite geodesy. Unlike earlier solutions our present determinations include very elaborate gravitational models containing hundreds of terms, precise worldwide positions good to ±10 ...

Irrigation Impact on Humid Heat Stress: Divergent Metrics, Vegetation Dynamics, and Future Worsening

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Irrigation impact on heat comfort is controversial due to its opposing effects of cooling and humidification, especially over the North China Plain under global warming. While heat stress indices exhibit different responses, the omission of dynamic vegetation adds further uncertainty.
