UAV‐based deep transfer learning to improve grain yield prediction in winter wheat across temporal and spatial variability

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Accurate prediction of grain yield (GY) remains a major challenge in plant breeding due to complex interactions between genotype, environment, and management (G × E × M) factors. Remote sensing data from unmanned aerial vehicles (UAVs) equipped with multispectral sensors have emerged as a pivotal resource for high‐throughput phenotyping.

High‐throughput assessment of plant stand establishment, seedling vigor, and light interception in peanut using UAV‐based RGB and multispectral imagery

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract In peanut (Arachis hypogaea L.), plant stand establishment, seedling vigor, and canopy growth are key determinants of crop performance; yet traditional ground‐based assessment methods can be destructive, labor‐intensive, and limited in throughput.

Evaluation of uncrewed aerial system‐derived vegetation indices for forage trait phenomic prediction in oat–pea intercrop breeding trials

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Accelerating genetic gain in intercrop forage breeding requires scalable phenotyping approaches that can capture both yield and quality variation across complex genotype combinations. This study evaluated the use of uncrewed aerial system (UAS)‐derived multispectral vegetation indices (VIs) for predicting forage yield and nutritive quality in ...

Phenomic prediction of wheat yield and grain quality using multispectral, hyperspectral, and thermal imagery

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Grain quality in durum wheat (Triticum turgidum L. subsp. durum (Desf.) Husn.) remains a major challenge for plant breeders because grain yield and grain protein concentration often show a trade‐off, and both are influenced by grain nitrogen concentration.

Exploring the Potential of Unmanned Aerial System‐Based Topographic Indices Maps to Evaluate Storm Drain Positioning

open access: yesJournal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT Urbanisation, climate uncertainty, and limited city budgets have heightened the need for efficient urban drainage management. While advanced hydrodynamic models assess the performance of drainage networks, they are computationally intensive, time‐consuming, and expensive.

High Resolution Focal Mechanisms and Stress Field Orientation in Southern Italy From Short‐Term Dense Arrays

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Understanding fault geometry and mechanics is key to interpreting the seismotectonic setting of a region. We analyze data from a 1‐year dense seismic array deployment in Southern Italy to infer focal mechanisms and stress field from low‐magnitude earthquakes using machine‐learning techniques.

Reevaluating Large‐Scale Deformation Precursors of Great Subduction Earthquakes: Insights From Satellite Gravity and GNSS Data

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Validating the controversial hypothesis that precursory gravity changes arise from sudden acceleration of subducting plates potentially triggering great earthquakes is of paramount importance. To rigorously evaluate proposed precursors for the 2011 Mw 9.0 Tohoku and 2010 Mw 8.8 Maule earthquakes, we develop a statistical framework that enables

The Overlooked Role of Alongshore Beach Non‐Uniformity in Short‐Term Shoreline Variability

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Long‐term beach monitoring and satellite‐derived shoreline products are typically validated, and shoreline models calibrated, along cross‐shore transects. Open sandy beaches, however, are rarely uniform alongshore, because crescentic megacusps migrate past fixed transects, and their effect on single‐transect records remains unquantified.

Analysis of GNSS-R delay and doppler tracking errors

open access: yes
The compensation of the delay and Doppler errors using tracking is important to accurately estimate the sea height in spaceborne GNSS-R. This work presents the impacts of the tracking residual errors on the GNSS-R observables, and potential tracking ...
