Merging Regional Climate Models and Remote Sensing Observations to Better Estimate Mountain Snow Water Equivalent

Water Resources Research, Volume 62, Issue 11, November 2026.
Abstract Large‐scale, high‐resolution estimation of snow water equivalent (SWE) in mountainous regions remains challenging. Continental‐scale approaches, including SWE reconstruction and regional climate model (RCM) simulations, are computationally expensive at high resolutions.

Systematic Discrepancies Should Be Addressed Before Effective Parameter Learning: Insights From Soil Moisture Simulations Using Differentiable Process‐Based Models

Water Resources Research, Volume 62, Issue 11, November 2026.
Abstract Differentiable hydrologic models combining neural networks with process‐based backbones—fully implemented or approximated by surrogate models—offer highly competitive accuracy and improved interpretability compared to either model type used alone.

Bayesian Calibration of Dynamic Models of Earthquake Sequences Using Observations From Past Large Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Physics‐based models of the earthquake cycle could be used for time‐dependent hazard assessment. For such an application, their parameters must be calibrated so that simulated earthquake sequences reproduce the statistics of past earthquakes, including recurrence statistics and magnitudes. This is challenging because the dynamics are described

Satellite Observations of Annual Variations in the Ocean‐Induced Magnetic Field From the Tropical Oceans

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract The Ocean Induced Magnetic Field (OIMF) is produced by the motion of the electrically conducting ocean through Earth's ambient magnetic field, and its time‐dependence carries information concerning ocean dynamics and electrical conductivity changes. Here, we present an algorithm to estimate, from satellite magnetic field observations, the band‐

Improvement of a Regional Multiscale NLS‐4DVar Assimilation System Based on the CWRF‐CoLM Coupled Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 11, November 2026.
Abstract Ensemble perturbations in 4DEnVar‐type methods are pulled in two directions at once: estimating a reliable background‐error covariance (BEC) calls for perturbations large enough to sample real error structure, while a valid tangent‐linear (TL) approximation calls for perturbations small enough to stay near‐linear.
