Asymmetry in the effect of North Atlantic sea surface temperature on the eddy‐driven jet

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Projections of climate over Europe and the Atlantic are uncertain due to the uncertainty surrounding future changes in North Atlantic sea surface temperatures (SSTs). Here, we demonstrate that warming in the North Atlantic Ocean is linked to a transition to a negative phase of the North Atlantic Oscillation, as well as to an equatorward displacement of

Applicability Analysis of InSAR Tropospheric Delay Correction for Landslide Monitoring Considering Periodicity Characteristics—Case Study on Southwest Mountainous Region

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Tropospheric delay is a major limitation in interferometric synthetic aperture radar (InSAR) for measuring landslide deformation. It exhibits complex spatial–temporal variability, stochastic behavior, and is particularly difficult to model in the ...

THE EFFECT OF SEASONAL VARIATION ON GNSS ZENITH TROPOSPHERIC DELAY [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The Global Navigation Satellite System (GNSS) signal experiences delays caused by the atmosphere, leading to the lengthening of the geometric path of the ray, commonly referred to as tropospheric delay. This delay is a significant source of error in GNSS

Multiscale numerical sensitivity simulations of a mesoscale gravity‐wave event

Quarterly Journal of the Royal Meteorological Society, EarlyView.
High‐resolution WRF simulations of the February 14–15, 1992 STORM‐FEST event show that mesoscale gravity‐wave genesis occurs via geostrophic adjustment within an upper‐level unbalanced jet, while wave ducting governs maintenance. High‐resolution (1 km), improved physical parameterization, and targeted sensitivity simulations demonstrate that upstream ...

Insights From the Alphasat Aldo Paraboni Experiment at Tito Scalo and Spino d'Adda: Characterizing Scintillation and Rain Attenuation at Ka‐ and Q‐Band Frequencies

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT We present experimental results on the relationship between rain attenuation and simultaneous scintillation during rain events, based on beacon signal measurements at 19.7 (Ka‐band) and 39.4 GHz (Q‐band) from the geosynchronous Alphasat satellite (25° E), received at two Italian ground stations, Spino d'Adda (42.1° slant path) and Tito Scalo ...

The Carbon Trap: Fragmentation, Accounting Hegemony, and Justice in Global Carbon Governance

Sustainable Development, EarlyView.
ABSTRACT Carbon accounting is increasingly treated as the technical foundation of global climate action, yet the rules through which emissions are measured, converted, attributed, and disclosed remain fragmented across national inventories, corporate reporting standards, supply‐chain boundaries, and trade‐related policy instruments.

Chemical Recycling as a Tool for Enabling a Second Life for Polyesters

SusMat, EarlyView.
This review presents the elucidation of the life cycle of main polyesters, detailing end‐of‐life methods, with focus of solvolysis technologies, then an analysis of LCA and TEA on literature data, an original data analytic, and, finally, a current industrial mapping of the main processes with a critical perspective on the plastic life‐cycle ecosystem ...

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.
