Rupture Directivity From Energy Envelope Deconvolution: Theory and Application to 58 Ridgecrest M 3.5–5.5 Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Earthquake rupture directivity impacts ground motions and provides insights on fault zone properties and earthquake physics. However, measuring directivity of small earthquakes is challenging due to their compact rupture sizes and complex path and site effects at high frequencies.

Implementing a Plant Hydraulics Parameterization in the Canadian Land Surface Scheme Including Biogeochemical Cycles (CLASSIC) v.1.4

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.
Abstract Drought conditions cause stress to terrestrial ecosystems and make their accurate representation in models challenging. The Canadian LAnd Surface Scheme Including biogeochemical Cycles (CLASSIC) employs an empirical approach to link soil moisture stress with stomatal conductance. Such approaches typically perform poorly during drought.

Accurate and Robust Sensing of the Ionosphere With Uncoded Long Pulse ISR Measurements: 1‐Lag Profile Inversion of Ion Composition and Temperature

Radio Science, Volume 61, Issue 1, January 2026.
Abstract Incoherent scatter radar probing of the topside F‐region ionosphere with reduced electron densities residing at relatively large radar ranges requires the use of uncoded long pulse (ULP) transmissions. In these ULP measurements the range resolution is necessarily poor, rendering the inference of ionospheric state parameters such as composition,

Accurate and Robust Sensing of the Ionosphere With Uncoded Long Pulse ISR Measurements: 2. Differential Drift Inversions Using Lag Profile Phase Data

Radio Science, Volume 61, Issue 1, January 2026.
Abstract A method of estimating heavy (O+) and light (H+ and He+) ion drift velocities in the topside F‐region ionosphere using Arecibo uncoded long pulse data is presented. We show that multi‐ion drift velocity estimation using long pulse ACF phase data requires accurate knowledge of ionospheric state parameters, such as temperatures and compositions,
