Explaining occurrences of auroral kilometric radiation in Van Allen radiation belts

Geophysical Research Letters, 2016
AbstractAuroral kilometric radiation (AKR) is a strong terrestrial radio emission and dominates at higher latitudes because of reflection in vicinities of the source cavity and plasmapause. Recently, Van Allen Probes have observed occurrences of AKR emission in the equatorial region of Earth's radiation belts but its origin still remains an open ...

Disappearance of plasmaspheric hiss following interplanetary shock [PDF]

, 2015
Plasmaspheric hiss is one of the important plasma waves controlling radiation belt dynamics. Its spatiotemporal distribution and generation mechanism are presently the object of active research.

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao

PLANTS, PEOPLE, PLANET, EarlyView.
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...

A pilot variational coupled reanalysis based on the CESAM climate model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

Resonant scattering of energetic electrons by unusual low-frequency hiss [PDF]

, 2014
We quantify the resonant scattering effects of the unusual low-frequency dawnside plasmaspheric hiss observed on 30 September 2012 by the Van Allen Probes. In contrast to normal (∼100-2000 Hz) hiss emissions, this unusual hiss event contained most of its

From Global Mapping to Local Action: Green Finance, Regulatory Frameworks, and Policy Transformation for Sustainable Energy Transition in Qatar and Türkiye

Sustainable Development, EarlyView.
ABSTRACT In 2024, global annual issuance exceeded USD 1.1 trillion mostly through green bonds, credits, and sustainability‐linked instruments, yet significant regional disparities remain. This article examines how Qatar and Türkiye, two hydrocarbon‐dependent but rapidly transitioning economies, are integrating green finance into their sustainability ...

Advancing Single‐Walled Carbon Nanotubes toward Next‐Generation Electronic Materials: The Critical Roles of Purity and Processability

Small Methods, EarlyView.
Single‐walled carbon nanotubes (SWNTs) are promising for a wide range of applications. In particular, their exceptional electrical conductivity positions them as potential alternatives to traditional metal conductors. This review identifies the key mechanisms governing their conductivity within composites and proposes practical pathways for translating

Can We Intercalibrate Satellite Measurements by Means of Data Assimilation? An Attempt on LEO Satellites

Space Weather
Low Earth Orbit satellites offer extensive data of the radiation belt region, but utilizing these observations is challenging due to potential contamination and difficulty of intercalibration with spacecraft measurements at Highly Elliptic Orbit that can
