Impact of Two Radio Occultation Constellations on Numerical Weather Prediction: Polar‐Orbits Only and Mixed Polar‐Equatorial Orbits

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract This study explores the relative impact of two orbital configurations for Global Navigation Satellite System radio occultation (RO) observations in numerical weather prediction using observing system simulation experiments (OSSE). Three experiments are carried out: a Control experiment with no RO observations and two experiments with 14,000 RO

Construction of a Global Atmospheric Refractivity Model for Optical Wavelengths Based on Temporal Evolution Characteristics

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Atmospheric refractivity model accuracy is important for refraction correction, starlight refraction navigation, and related optoelectronic applications. To address the insufficient understanding of refractivity temporal evolution and the lack of clear criteria for selecting model temporal resolution, this study constructs a global four ...

Determination of Earth's Static Gravity Field Using Quantum Gravity Satellites at Very Low Earth Orbit

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Very Low Earth Orbit (VLEO) satellite platforms and quantum‐optical sensing technologies may provide new observation approaches for improving Earth's static gravity field models. This study conceptually assesses their potential contribution through a two‐tier closed‐loop simulation framework.

Provenance of the Middle‐Upper Triassic Songpan‐Ganzi Flysch of Western China Revealed by Anisotropy of Magnetic Susceptibility Measurements: Implications for the Tectonic‐Paleogeographic Evolution of the Paleo‐Tethys Ocean

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The Triassic Songpan‐Ganzi turbidite complex (SGC) on the eastern Tibetan plateau is one of the largest flysch turbiditic complexes on Earth. However, the provenance of its extremely thick turbidites is hotly debated. We conducted the measurement of anisotropy of magnetic susceptibility (AMS) of Triassic turbidites from nine profiles in Ruo ...

Full‐Waveform Seismic Tomography of the Upper Mantle Beneath the Arabia‐Eurasia Collision Zone

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Despite being one of the most recent major orogenic events, the timing of the Arabia‐Eurasia collision is still debated. Much of the discrepancy arises due to uncertainties over the amount of continental subduction of the Arabian passive margin and the timing of a hard collision of cratonic Arabian lithosphere with Eurasia.
