Revisiting Sub‐Surface Drought Cascades With Daily Satellite Observations of Soil Moisture and Terrestrial Water Storage

open access: yesWater Resources Research, Volume 61, Issue 8, August 2025.
Abstract The increasing frequency, intensity, and duration of extreme heat and drought events in a warming climate make it crucial to understand the relationship between surface and subsurface water storage dynamics during these events. Changes in water storage can be studied globally using satellite observations.

Evaluating Richards Equation and Infiltration Capacity Approaches in Mesoscale Hydrologic Modeling

open access: yesWater Resources Research, Volume 61, Issue 8, August 2025.
Abstract This study compares two widely used approaches for modeling soil moisture (SM) infiltration in mesoscale hydrology: the one‐dimensional Richards equation (1D RE), which governs vertical flux exchange but is nonlinear and computationally demanding, and the infiltration capacity (IC) scheme, which is simpler and restricts SM movement to the ...

Spatial Distribution and Plasmaspheric Ducting of Auroral Kilometric Radiation Revealed by Wind, Polar, and Arase

open access: yesAGU Advances, Volume 6, Issue 4, August 2025.
Abstract Auroral Kilometric Radiation (AKR), the dominant radio emission from Earth, has been extensively studied, though previous analyses were constrained by limited spacecraft coverage. This study utilizes long‐term observations from Polar, Wind, and Arase spacecraft to generate comprehensive global AKR occurrence rate maps, revealing a high ...

Simulation of Galactic Cosmic Ray Proton Fluxes With the Daily Modulation Parameter: Validation With AMS‐02 Data for 2011–2019

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.
Abstract The flux of galactic cosmic rays (GCRs) is modulated by solar activity on different time scales. This is often described with the force‐field approximation via the single variable parameters of the modulation parameter, which formally corresponds to the average rigidity loss of GCR particles in the heliosphere. The force‐field approximation is
