TL;DR: In this paper, the physical processes affecting the dynamics of the Earth's particle radiation environment are reviewed along with scientific and engineering models developed for its description, focusing on models that are either operational engineering models or models presently under development for this purpose.

TL;DR: In this article, the authors evaluate the exposure during nadir observations with JEM-EUSO, the Extreme Universe Space Observatory, on-board the Japanese Experiment Module of the International Space Station.

TL;DR: THOR as discussed by the authors is a single-spacecraft mission with an orbit tuned to maximize data return from regions in near-Earth space - magnetosheath, shock, foreshock and pristine solar wind - featuring different kinds of turbulence.

TL;DR: Three-dimensional radio interferometric observations of lightning over the Netherlands reveal small needle-shaped plasma structures associated with the positive leader channels, explaining why cloud-to-ground lightning connects to the ground multiple times.

TL;DR: In this article, a coronal shock associated with a CME and type II radio burst was found to be located at the expanding flank of the CME, where the shock geometry is quasi-perpendicular with θ Bn ~ 70°.
