Earth's radiation belts' ions: patterns of the spatial-energy structure and its solar-cyclic variations [PDF]

open access: yesAnnales Geophysicae, 2020
Spatial-energy distributions of the stationary fluxes of protons, helium, and ions of the carbon–nitrogen–oxygen (CNO) group, with energy from E ∼100 keV to 200 MeV, in the Earth's radiation belts (ERBs), at L∼1–8, are considered here using

Space-to-space very low frequency radio transmission in the magnetosphere using the DSX and Arase satellites

open access: yesEarth, Planets and Space, 2022
Very low frequency (VLF) waves (about 3–30 kHz) in the Earth’s magnetosphere interact strongly with energetic electrons and are a key element in controlling dynamics of the Van Allen radiation belts.

Survey of ELF-VLF plasma waves in outer radiation belt observed by Cluster STAFF-SA experiment [PDF]

open access: yesAnnales Geophysicae, 2008
Various types of plasma waves have profound effects on acceleration and scattering of radiation belt particles. For the purposes of radiation belt modeling it is necessary to know statistical distributions of plasma wave parameters.

Balanced Low Earth Satellite Orbits

open access: yesAdvances in Astronomy, 2020
The present work aims at constructing an atlas of the balanced Earth satellite orbits with respect to the secular and long periodic effects of Earth oblateness with the harmonics of the geopotential retained up to the 4th zonal harmonic.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Global patterns of treeline predictability and the gap between the forest and the treeline

open access: yesEcography, EarlyView.
The alpine treeline is the highest elevation at which trees can grow, which is assumed to be controlled by temperature and globally predictable. However, many upper forest limits (UFLs) do not reach this elevation, due natural factors and human disturbance.
