SMWPF: a cloud-edge collaborative network enabled by large-small model collaboration for wind speed prediction

Accurate wind speed forecasting is increasingly important for supporting reliable wind power grid integration and enhancing early warning of extreme wind events. Existing spatiotemporal models can fuse multiple meteorological variables and perform well in medium-resolution wind f...

Tackling carbon price volatility: A synchronous joint-decomposition and multi-scale spatiotemporal feature learning for interval-valued forecasting

Precise carbon prices forecasting is important for the optimal allocation of resources within carbon markets. While research has shifted from point forecasting to interval forecasting, the non-linear, non-stationary, and dynamical interval-valued carbon price volatility continue...

Green manure species composition differentially regulates soil N₂O emissions and their environmental drivers in subtropical tea plantations

Green manure intercropping is widely advocated for improving soil fertility in perennial cropping systems, yet its effects on soil N₂O emissions remain poorly quantified in tea plantations. This study assessed N₂O fluxes under three intercropping regimes, i.e., no intercropping (...

Condensation Sink Efficiency of Atmospheric Particles Regulated by Their Chemical Compositions and Hygroscopicity

Abstract Condensation sink (CS) from atmospheric pre-existing particles is a crucial limiting factor for the occurrence of new particle formation (NPF). However, intense NPF events occur frequently in polluted urban areas despite high CS levels. Here, to address this discrepancy,...

Multidecadal Changes in Atmospheric Dryness Over East Asia Dominated by Internal Climate Variability

Abstract Summer near‐surface vapor pressure deficit (VPD), a key measure of atmospheric dryness, has increased markedly across East Asia since 1980, yet the relative roles of external forcing and internal variability (IV) in its multidecadal changes remain unclear. Here we show t...

Fractal Dimension of Shallow Cumulus Cloud Boundaries Beyond Bulk Fractal Scaling

Abstract Cloud boundaries reflect turbulent mixing and cloud–environment interactions, but their geometric complexity remains poorly quantified. Here, we investigate the complexity of shallow cumulus cloud edge using two fractal approaches: the bulk area–perimeter method and the...

IIGF-Net: An interpretability-driven intensity-geometry fusion framework for shield tunnel leakage segmentation in 3D point clouds

Automated leakage detection from MLS-acquired 3D point clouds is essential for the preventive maintenance of shield tunnels. However, existing deep learning methods must reconcile the use of physically grounded handcrafted descriptors with the opaque representations learned by hi...

Molecular evolution of oxygenated organic molecules in a cloud-influenced forested mountain environment

Abstract. Atmospheric oxygenated organic molecules (OOMs) link the oxidation of volatile organic compound to secondary organic aerosol formation, yet their molecular evolution in cloud-influenced forested mountain environments remains poorly constrained. Here, gas-phase OOMs were...

When Does ESG Enhance Export Resilience? The Moderating Role of ESG in the Innovation Response to Trade Policy Shocks

Maintaining export resilience against trade policy shocks is a critical challenge for industrial exporters amid rising global trade protectionism. Treating the 2018 US–China trade friction as a quasi-natural experiment, this study examines the interactive effects of research and...

Surface Nucleation‐Mode Particles Increase During Intense Vertical Exchange Between the Atmospheric Boundary Layer and the Free Troposphere

Abstract Vertical exchange between the atmospheric boundary layer (ABL) and the free troposphere (FT) is a key pathway for aerosol transport and can substantially influence surface air quality. In this study, an intense ABL‐FT exchange event over Shanghai on 29 March 2024 was cap...

Supersaturation Fluctuation Modulates Warm Rain Formation in Cumulus Clouds: Implications for Hygroscopic Cloud Seeding

Abstract Recent observational studies have demonstrated that supersaturation fluctuations (SS’) in clouds induced by turbulence at scales smaller than 100 m can significantly affect microphysical processes such as aerosol activation and droplet condensation. However, subgrid‐scal...

Physics-constrained transfer learning with a spectral-fidelity-preserving model for satellite remote sensing applications

Abstract. Accurate spectral transformation across satellite sensors with similar but different spectral response functions (SRFs) are essential for applying the same retrieval algorithms. A novel physics-constrained transfer learning (TL) framework is developed for transferring s...

Physics-Guided Residual Learning for Full-Angular-Domain Scattering Prediction of Coding Metasurfaces

Coding metasurfaces provide an effective approach for manipulating electromagnetic scattering through discrete coding states. However, obtaining angular-domain scattering responses for a large number of coding configurations remains computationally expensive with full-wave electr...

High‐Entropy Perovskites for Solid Oxide Cells: Mechanistic Insights to Practical Applications

ABSTRACT Solid oxide cells (SOCs) are high‐temperature electrochemical platforms for efficient energy conversion and chemical production in both fuel‐cell and electrolysis modes. Practical deployment remains constrained by fuel‐electrode coking, limited transport, and sluggish ki...

Anthropogenic modulation of ice-nucleating particles over the Yellow and East China Seas: Shipboard observations and single-particle analysis

To address the scarcity of observational data on atmospheric ice-nucleating particles (INPs) over the mixed marine-continental environments of East Asia, shipboard measurements were conducted over the Yellow Sea (YS) and East China Sea (ECS) in April 2022. Aerosol samples were co...

Integrated retrieval of ocean surface wind and current fields from single-geometry SAR observations through a physically constrained Bayesian framework

Ocean surface winds and currents are coupled through air–sea interaction but are commonly retrieved independently from spaceborne synthetic aperture radar (SAR). For operational single-geometry SAR, simultaneous wind–current retrieval is underdetermined and remains reliant on bac...

Adaptive Graph Learning with Persona-Aware Attribution for Event-Resilient Metro Passenger Flow Prediction

Urban rail passenger flow forecasting, based on large-scale automatic fare collection (AFC) sensor networks, is typically evaluated on ordinary days, yet operators most need accurate predictions during event days. The AFC infrastructure comprises 191 sensor-equipped stations with...
