Characteristics of Boundary Layer Height Variations in Global Arid Regions and Their Sensitivity to Influencing Energy Factors

International Journal of Climatology, EarlyView.
Global warming has intensified drought impacts across most arid regions, altering surface energy partitioning and atmospheric boundary layer (ABL) development. Using 1979–2018 ERA‐Interim reanalysis data, we show that the long‐term mean boundary layer height (BLH) over global arid regions is approximately 841.8 m, nearly 200 m higher than over humid ...

Assessing plant water status: Part 2 – Non‐destructive and remote sensing approaches

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Precise, real time and non‐destructive assessment of plant water status is important for advancing plant physiological understanding, optimizing water usage, improving crop resilience and supporting precision agriculture in the face of increasingly variable climatic conditions.

Revealing Dust Source Changes in East Asia From Past to Future: An Interpretable Deep Learning Approach

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian dust source areas are controlled by climate and human activities and are closely associated with land degradation, yet their long‐term evolution under global warming remains insufficiently quantified. An integrated framework that couples a U‐Net segmentation model with Shapley Additive Explanations (SHAP) was built to map and attribute

Eroding Confidence in Gully Location Risk Prediction in Mine Pit Rehabilitation

Land Degradation &Development, EarlyView.
ABSTRACT Understanding how rehabilitation measures, such as landform shaping, and surface finishes impact gully erosion risk could assist in designing less erosive rehabilitation. In this study we use high resolution digital elevation models of rehabilitated mine pits to explore risk factors for gully formation.
