Effects of energetic electrons on the electrodynamics in the ionosphere [PDF]
Annales Geophysicae, 2004 From the observations by the PIXIE and UVI cameras on board the Polar satellite, we derive global maps of the precipitating electron energy spectra from less than 1keV to 100keV. Based on the electron spectra, we generate instantaneous global maps of

Cosmic Inflation from Emergent Spacetime Picture
, 2016 We argue that the emergent spacetime picture admits a background-independent formulation of cosmic inflation. The inflation in this picture corresponds to the dynamical emergence of spacetime while the conventional inflation is simply an (exponential ...

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review
Reviews of Geophysics, Volume 64, Issue 1, March 2026.Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...

Multivariate analysis of nonlinearity in sandbar behavior [PDF]
Nonlinear Processes in Geophysics, 2008 Alongshore sandbars are often present in the nearshore zones of storm-dominated micro- to mesotidal coasts. Sandbar migration is the result of a large number of small-scale physical processes that are generated by the incoming waves and the interaction ...

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Soil production, through bedrock weathering, regulates landscape evolution, biogeochemical cycles, and societal sustainability, yet quantifying soil production rates (SPRs) remains difficult due to limited tools. Here, we present a new framework for measuring SPRs based on uranium comminution ages and validate this approach at a deep granitic ...

AGU Advances, Volume 7, Issue 1, February 2026.Abstract Energetic electron precipitation plays a pivotal role in shaping Earth's radiation belt dynamics and drives significant physical and chemical changes in the upper atmosphere. However, the detailed mechanisms governing the loss of relativistic electrons have remained unclear, largely due to the limited energy coverage and coarse resolution of ...

Mean velocities measured with the double pulse technique [PDF]
Annales Geophysicae, 2004 It was recently observed that double-pulse measurements of the mean velocities of a wide asymmetric spectrum are a function of the time lag between the pulses (Uspensky et al., 2004).

Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract The longest known Aletai meteorite belt presents a unique phenomenon in meteoroid dynamics. To investigate its formation mechanism, this study introduces a bilobate‐shaped meteoroid model, emphasizing aerodynamic interactions and structure evolution.
