The Scale Length of Electron Cyclotron Harmonic Wave Power by MMS Satellites

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Using four MMS satellites from 2015 to 2021, we statistically investigate Electron Cyclotron Harmonic (ECH) wave power scale lengths. These waves are categorized into three distinct populations based on the background magnetic field topology: equatorial, off‐equator, and near the magnetopause.

EISCAT/CRRES observations: Nightside ionospheric ion outflow and oxygen-rich substorm injections [PDF]

, 1996
We present combined observations made near midnight by the EISCAT radar, all-sky cameras and the combined released and radiation efects satellite (CRRES) shortly before and during a substorm.

Mapping Leopard Conservation Priorities in Southeast Asia

Ecology and Evolution, Volume 16, Issue 11, November 2026.
The Critically Endangered Indochinese leopard (Panthera pardus delacouri) is restricted to < 4% of its historical range across Southeast Asia by poaching, habitat loss and prey depletion. Using resistant kernel modelling through the CoLa Decision Support System, we present the first connectivity analysis for the subspecies across its extant and former ...

Evaluating Machine‐Learning Weather Prediction for UK Windstorm Weather Warnings

Meteorological Applications, Volume 33, Issue 6, November/December 2026.
Can machine‐learning weather prediction models simulate UK windstorms well enough to be used when providing wind weather warnings? We evaluate them against current numerical weather models, finding that they are not yet suitable to replace them, particularly when hazardous winds are linked to sharp frontal gradients and mesoscale features.

Latitude variation of radar aurora with local substorm activity

, 1970
Radio aurora detected at Prince Albert advances farther south with increasing magnetic activity. The latitude vs. magnetic activity relation for radio aurora is compared with similar relations for ionospheric currents.

River Ice Processes Modelling: A Comprehensive Review

River Research and Applications, Volume 42, Issue 9, Page 1823-1838, November 2026.
ABSTRACT River ice strongly influences hydrology, hydrodynamics, and ecosystems in cold regions, with an impact on flooding, hydropower generation, navigation, and aquatic habitats. Modeling river ice processes is therefore essential for both scientific understanding and operational management.

Variability of dayside convection and motions of the cusp/cleft aurora [PDF]

, 1993
We present measurements of the ionospheric plasma flow over the range of invariant latitudes 71-76-degrees, observed at 10-second resolution using both the EISCAT radars, with simultaneous observations of the 630 nm cusp/cleft aurora made by a meridian ...

Empirical Parameterizations of ULF Power and Drift Orbit Averaged Radial Diffusion Coefficients From Ground Magnetometers for Different MLT

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Radial diffusion, driven by ultra‐low frequency (ULF) waves, is an important process for the transport of electrons in the outer radiation belt. Ground magnetometers give us constant observations of such ULF waves but their usefulness is limited by the models used to transform ground measurements into their progenitor fields in space.

Carbon Processing Domains: Seasonal and Spatial Controls on Dissolved Organic Carbon in a Montane River

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 11, November 2026.
Abstract Lotic biogeochemical structure and function have been studied extensively, but rivers lack a functional classification system for assessing spatiotemporal variability in solute behavior. Dissolved organic carbon (DOC) is a basal resource for aquatic communities, is chemically complex, and has aquatic and terrestrial sources and sinks. DOC is a

Van Allen Probes Observations of a Fundamental Poloidal Wave in the Plasmasphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract All past spacecraft observations of fundamental poloidal Alfvén (P1) waves attributed to ion drift resonance have been made outside the plasmasphere. In this study, we present the first spacecraft observations of a plasmaspheric P1 wave driven by that resonance.
