Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract Enhancing the applicability of Gravity Recovery and Climate Experiment (GRACE) products poses challenges due to the trade‐off between the temporal and the spatial resolution within limits posed by the mission design. If a Kalman filter framework was adopted to characterize the relationship between monthly and finer temporal scales, it could ...

Empirical Assessment of Storm‐Time Thermospheric Density Inversion Methods From LEO POD Data
Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract Thermospheric mass density is one of the largest sources of operational uncertainty for spacecraft in low Earth orbit, particularly during geomagnetic storms. The growing population of Global Navigation Satellite System‐equipped satellites presents a data set of opportunity: precise orbit determination (POD) data streams can be used to ...

The ASTE‐BGC Data‐Assimilative Regional Ocean Biogeochemical Model
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.Abstract We present a data‐assimilative regional ocean biogeochemical model, ASTE‐BGC, which simulates the physical and biogeochemical state of the North Atlantic Ocean from 2002 to 2017. Model physics are provided by a physical state estimate (ASTE), which assimilates O(109) in situ and satellite‐based observations over the model domain and time ...

Radio Science, Volume 61, Issue 8, August 2026.Abstract Accurate specification of the ionosphere is essential for mitigating the impacts of space weather on communication, navigation, and surveillance systems. ANCHOR is a newly developed ionospheric data assimilation (DA) model from the U.S. Naval Research Laboratory that fuses measurements from ionosondes, radio occultation, and Global Navigation ...

Assessment of Spacecraft Internal Charging in the Earth's Outer Radiation Belt
Space Weather, Volume 24, Issue 8, August 2026.Abstract The internal charging effects triggered by energetic (>100 keV) electrons in the Earth's radiation belts can cause anomalies and failures of electronic components aboard spacecraft. Given the critical importance of safeguarding space assets, it is essential to estimate internal charging risks, which depend highly on the distribution of ...

Water Resources Research, Volume 62, Issue 8, August 2026.Abstract Accurate identification of nonaqueous phase liquid (NAPL) contamination sources is critical in pollution management. However, the joint inversion of source characteristics and heterogeneous hydrogeological parameters faces two major challenges.
