Relativistic surfatron process for Landau resonant electrons in radiation belts [PDF]
Nonlinear Processes in Geophysics, 2014 Recent theoretical studies of the nonlinear wave-particle interactions for relativistic particles have shown that Landau resonant orbits could be efficiently accelerated along the mean background magnetic field for propagation angles θ in close proximity

What effect do substorms have on the content of the radiation belts? [PDF]
J Geophys Res Space Phys, 2016 Substorms are fundamental and dynamic processes in the magnetosphere, converting captured solar wind magnetic energy into plasma energy. These substorms have been suggested to be a key driver of energetic electron enhancements in the outer radiation ...

NARX Neural Network Derivations of the Outer Boundary Radiation Belt Electron Flux
Space Weather, 2022 We present two new empirical models of radiation belt electron flux at geostationary orbit. GOES‐15 measurements of 0.8 MeV electrons were used to train a Nonlinear Autoregressive with Exogenous input (NARX) neural network for both modeling GOES‐15 flux ...

Using MEPED observations to infer plasma density and chorus intensity in the radiation belts
Frontiers in Astronomy and Space Sciences, 2022 Efforts to model and predict energetic electron fluxes in the radiation belts are highly sensitive to local wave-particle interactions. In this study, we use multi-point measurements of precipitating and trapped electron fluxes to investigate the dynamic

Space weather effects on the MAGION-4 and MAGION-5 solar cells [PDF]
Annales Geophysicae, 2005 Data on solar array efficiency measured on board two Czech MAGION micro-satellites between August 1995 and June 2002, during the period of increasing and high solar activity, were used to study the space weather effects on photo-voltaic solar cells. A

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Observations of Radiation Belt Losses Due to Cyclotron Wave-Particle Interactions [PDF]
, 2020 Electron loss to the atmosphere plays a critical role in driving dynamics of the Earths Van Allen radiation belts and slot region. This is a review of atmospheric loss of radiation belt electrons caused by plasma wave scattering via Doppler-shifted ...

The global response of relativistic radiation belt electrons to the January 1997 magnetic cloud [PDF]
, 1998 In January 1997 a large fleet of NASA and US military satellites provided the most complete observations to date of the changes in \u3e2 MeV electrons during a geomagnetic storm. Observations at geosynchronous orbit revealed a somewhat unusual two-peaked

Constraining the Location of the Outer Boundary of Earth's Outer Radiation Belt
Earth and Space Science, 2021 Characterizing the location of the outer boundary of the outer radiation belt is a key aspect of improving radiation belt models and helps to constrain our understanding of the mechanisms by which the source and seed electron populations are transported ...
