Comparing Electron Radiation Belts and New Lessons from Jupiter [PDF]

, 2019
We revisit comparisons between the electron radiation belts of all of the strongly magnetized planets of the solar system; specifically those of Earth, Jupiter, Saturn, Uranus, and Neptune.

Discriminating Arid Ecosystems and Tracking Desertification Dynamics: Evidence From Grain‐Size End‐Member in the Manas River Basin, Northern Tianshan Mountains

Land Degradation &Development, EarlyView.
ABSTRACT The ecosystem of the Manas River Basin, composed of mountains, oases, and deserts, constitutes an ideal natural laboratory for investigating surface processes and environmental evolution in arid regions. Elucidating the provenance, transport dynamics, and climate response mechanisms of surface sediments in this system is critical for advancing

Research advances in the data assimilative modeling of the Earth's radiation belt electrons

地球与行星物理论评
The Earth's radiation belts are regions where high-energy charged particles congregate in near-Earth space. Given that high-energy particles in the radiation belts pose a severe threat to the safety of spacecraft in orbit and astronauts, it is of vital ...

Cropland Suitability–Use Mismatches and Differentiated Zoning Regulation in the North China Plain: Implications for Spatially Optimised and Sustainable Land Use

Land Degradation &Development, EarlyView.
ABSTRACT Cropland distribution is often shaped by historical cultivation patterns rather than natural suitability, leading to mismatches between actual land use and agricultural production potential. However, their extent and spatial characteristics remain insufficiently understood in the North China Plain, one of China's most important grain‐producing

Annual–Perennial Forage Mixtures Improve Forage Productivity and Soil Quality in Patchily Degraded Cultivated Pastures Under Grazing Management

Land Degradation &Development, EarlyView.
ABSTRACT Patchy degradation of cultivated pastures under long‐term grazing is a serious issue limiting grassland productivity. The use of annual and perennial legume–grass mixtures, which offer complementary functional advantages, may provide a practical reseeding‐based approach for improving patchily degraded cultivated pastures; however, limited ...

Characteristic times for radiation belt drift phase mixing

Frontiers in Astronomy and Space Sciences
Impulsive radial transport events occurring in the radiation belts leave lasting marks in the form of drift echoes, that is, energy-dependent drift phase structures in the radiation belts that evolve at the drift frequency.
