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

Spaceborne to UAV Bistatic Radar System for High-resolution Imaging and Autonomous Navigation [PDF]

, 2010
Bistatic radars offer several advantages when compared to their monostatic counterparts. In addition to increased per- formance, sensitivity, coverage and revisit times, all of them parameters which are mainly dependent on their spatial configuration ...

Application of Quasi-Continuous Waveform Coding in Spaceborne Synthetic Aperture Radar

Remote Sensing
Quasi-continuous wave radar is an attempt to give consideration to the performance of pulse and continuous wave radar signals. However, it also has the shortcomings of both.

Tracking Slow‐Moving Landslide Responses to the 2023 Kahramanmaraş Earthquake With InSAR

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Strong earthquakes can have a dual impact on the slow‐moving landslide budget of a landscape by either triggering new actively deforming hillslopes or stabilizing existing ones. However, their regional‐scale influence on hillslope processes remains poorly understood because of limited observational coverage and the masking effects of long ...

Diffusion‐Based Reconstruction of Western North Pacific Surface Winds From CYGNSS for Tropical Cyclone Analysis

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract Sea surface wind retrieval under extreme weather conditions is constrained by the sparse and irregular spatiotemporal sampling of Global Navigation Satellite System Reflectometry (GNSS‐R). This study presents a probabilistic wind field reconstruction framework for the Western North Pacific using Score‐Based Data Assimilation (SDA). A diffusion

On the Timescales of Atmospheric Adjustments to Contrail Cirrus Formation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Condensation trails (contrails) that evolve into contrail cirrus may constitute the largest contribution to aviation's climate impact. However the strength and timescales of the adjustments of the upper atmospheric water budget to contrail formation are poorly known. Thanks to multiple simulations with the ICOLMDZ climate model, the relatively

A Concept for a High Performance Reflector-Based X-Band SAR [PDF]

, 2010
The success of current spaceborne Synthetic Aperture Radar (SAR) is boosting the performance requirement of next generation systems. In order to cope with the evolution of SAR the design of the new systems will need to meet higher requirements for ...

Concurrent Cloud and Drizzle Observations From Synergistic Ground‐Based Measurements

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Drizzle, a common feature of marine boundary layer clouds formed through collision‐coalescence, plays a key role in cloud microphysics and evolution. However, simultaneously retrieving cloud and drizzle properties from remote‐sensing observations remains challenging because drizzle droplets often dominate radar signals, masking cloud ...
