Collapses of Hemispheric Available Potential Energy
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract The atmospheric circulation in the midlatitudes is maintained against dissipation by converting available potential energy (APE) into kinetic energy (KE). During boreal winter this energy reservoir occasionally collapses, releasing up to 10% of hemispheric APE within days.

Andean tectonics: Implications for Satellite Geodesy [PDF]
Current knowledge and theories of large scale Andean tectonics as they relate to site planning for the NASA Crustal Dynamics Program's proposed high precision geodetic measurements of relative motions between the Nazca and South American plates are ...

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract As global climate change intensifies, hurricane‐induced storm surges are becoming more frequent and severe. While Global Navigation Satellite System‐Interferometric Reflectometry (GNSS‐IR) is widely used to monitor sea level variations, its capability to detect rapid and extreme events remains limited.

Satellite geodesy: Data acquisition
Eos, 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 ...

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract The Ross Ice Shelf (RIS) in West Antarctica experienced extensive surface melting in January 2016, driven by warm humid air transported from over the Southern Ocean. Few studies have reported increased atmospheric water vapor and turbulent mixing during this event in this region, where the availability of surface measurements is challenging ...

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract The Curie Point Depth (CPD) is a key thermal boundary in the deep lithosphere and is widely used to constrain its thermal structure. However, uncertainties in magnetization and the non‐uniqueness of inversion lead to considerable inter‐study differences.

Analysis of the Dihedral Corner Reflector’s RCS Features in Multi-Resource SAR
Applied SciencesArtificial corner reflectors are widely used in the vegetated landslide for time series InSAR monitoring due to their permanent scattering features. This paper investigated the RCS features of a novel dihedral CR under multi-resource SAR datasets. An RCS

Topographic Effects in Geoid Determinations
Geosciences, 2018 Traditionally, geoid determination is applied by Stokes’ formula with gravity anomalies after removal of the attraction of the topography by a simple or refined Bouguer correction, and restoration of topography by the primary indirect topographic ...

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract We use recently compiled GNSS velocities across the Zemuhe‐Daliangshan fault zone, part of the central Xianshuihe‐Xiaojiang fault system, to reconcile a long‐standing mismatch between geodetic and geologic slip‐rate estimates. We show that conventional elastic dislocation models yield slip rates and locking depths that conflict with seismic ...
