Record‐Breaking Easterly Dust Transport From North Africa to the Arctic: An Observational Study

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Mineral dust drives Arctic climate variability, but accurate source attribution remains difficult due to plume mixing from the different regions. Using observations and HYSPLIT modeling, we characterize a record‐breaking trans‐continental dust intrusion (March 13–19, 2013) traversing from North Africa to the Arctic. Distinct from single‐source

Local determination of ionospheric plasma convection from coherent scatter radar data using the SECS technique [PDF]

, 2010
A new technique for merging line-of-sight (LOS) data of the ionospheric plasma convection velocity, as obtained from coherent scatter radars, into a full velocity vector field on a sphere is presented.

A two-parameter wind speed algorithm for Ku-band altimeters [PDF]

, 2002
Globally distributed crossovers of altimeter and scatterometer observations clearly demonstrate that ocean altimeter backscatter correlates with both the near-surface wind speed and the sea state.

Structure–Property Relationship‐Guided Mechanisms for Electromagnetic Wave Absorption, Triboelectric Generation, and Negative Permittivity in Magnetic Metacomposites

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The composition and structural characteristics of metacomposites are crucial for tuning their negative electromagnetic parameters; however, the lack of a clear structure–property relationship severely limits their application in dielectric and magnetic fields.

A backscattering and propagation model for radar sounding of ice sheets [PDF]

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
In this paper the electromagnetic properties of the continental ice sheets are modeled with the aim of assessing the feasibility of space-based radar ice sounding at P-band. The paper focuses on the model itself, as distinct from the estimation of model parameters and the exploitation of the model.

Assimilation of Satellite‐Based Forest Biomass, Productivity and Leaf Area Index in a Global Land Model Incorporating Parameter Spatial Variations and Age Effects

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Disturbances profoundly impact forest capacity for sequestering and storing carbon, and the recovery rates after disturbances vary geographically. Many terrestrial carbon models inadequately simulate the effects of forest disturbances on biomass due to their reliance on equilibrium assumptions, the absence of historical disturbance data, as ...
