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.

Specifying High Altitude Electrons Using Low‐Altitude LEO Systems: Updates to the SHELLS Model
Space Weather, 2023 We describe a new version of the SHELLS model, which specifies the outer electron belt environment as observed by the Van Allen Probes using the Kp Index and data from Polar‐orbiting Operational Environmental Satellites and the Meteorological Operational

A data assimilation-based forecast model of outer radiation belt electron fluxes
Earth and Planetary Physics, 2023 Because radiation belt electrons can pose a potential threat to the safety of satellites orbiting in space, it is of great importance to develop a reliable model that can predict the highly dynamic variations in outer radiation belt electron fluxes.

Outer radiation belt and inner magnetospheric response to sheath regions of coronal mass ejections: a statistical analysis [PDF]
Annales Geophysicae, 2020 The energetic electron content in the Van Allen radiation belts surrounding the Earth can vary dramatically at several timescales, and these strong electron fluxes present a hazard for spacecraft traversing the belts.

Wave acceleration of electrons in the Van Allen radiation belts
Nature, 2005 The Van Allen radiation belts are two regions encircling the Earth in which energetic charged particles are trapped inside the Earth's magnetic field. Their properties vary according to solar activity and they represent a hazard to satellites and humans in space.

Frontiers in Astronomy and Space Sciences, 2021 The plasmapause marks the limit of the plasmasphere and is characterized by a sudden change in plasma density. This can influence the other regions of the magnetosphere, including due to different waves circulating inside and outside the plasmasphere. In
