Uncertainty Propagation From Radio Occultation Profiles to Aggregated Atmospheric Gridded Fields
Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract Radio occultation is a well‐established remote sensing method that provides reliable estimates of atmospheric profiles of diverse variables, including temperature and pressure. However, as with all indirect methods, radio occultation has some inherent systematic and random error effects, which lead to observational uncertainties.

Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract The limits of detection for earthquake surface deformation in the spatial domain have improved with advances in remote sensing imagery data availability, resolution, and analysis. Sub‐pixel correlation and digital elevation model (DEM) differencing from sub‐meter, earthquake‐spanning satellite optical imagery has enhanced surface rupture ...

Evaluate the Prediction Level of Polar Motion Interpolation for 6 hr in Ideal and Real Environments
Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract With the increasing demands for global development, deep space exploration missions are taking place more frequently, rendering the traditional 24‐hr Polar Motion (PM) predictions inadequate for supporting the frequent operations of spacecraft.

CSSR: a 2For1 Compressive Sensing Software Receiver with Combined Correlation For GPS-CA and Galileo-OS Signals [PDF]
, 2015 This is a 2for1 receiver because it acquires both GPS and Galileo signals at less than 50% of the complexity and processing time required by a Matched Filter acquisition receiver. CSSR is a new implementation of a dual-GNSS-signal Software Receiver using,

Evolution of Ionospheric Ion Upflow Flux During the April 2023 Geomagnetic Storm
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract We study the impact of the evolving magnetosphere‐ionosphere‐thermosphere system on upward ion fluxes during the 23–24 April 2023 geomagnetic storm. This storm has a “double‐dip” structure where two southward IMF Bz ${\mathrm{B}}_{z}$ periods cause two dips in the SYM‐H index.

Probing the Flyby Anomaly with the future STE-QUEST mission
, 2012 In this study, we demonstrate that the flyby anomaly, an unexpected acceleration detected in some of the gravitational assists of the Galileo, NEAR, Cassini and Rosetta spacecraft, could be probed by accurate orbital tracking available in the proposed ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract Establishing a quantitative framework to evaluate the spatiotemporal patterns of slow earthquakes and to detect their anomalous activities is essential for understanding diverse slip behaviors on plate boundaries and seismic hazard assessment. In this study, we focus on deep tectonic tremors, which are one manifestation of slow earthquakes and

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 1, January 2026.Abstract Most of Earth's present‐day terrestrial surface is covered by regolith—the layers of soil, saprolite, and weathered bedrock that together comprise the critical zone. Recent research has focused on understanding fluxes of minerals, water, and energy through the critical zone under steady state assumptions.
