Evidence for lunar tide effects in Earths plasmasphere

Lunar tides affect Earths oceans and its geomagnetic field. Multi-satellite observations demonstrate that they also impact the plasmasphere. Read more.

Contribution of Kinetic Alfven Waves to Energetic Electron Precipitation from the Plasma Sheet during a Substorm

Kinetic Alfven waves have been previously observed to be ubiquitously associated with magnetospheric electron injections but have not been considered as an important driver for precipitation of plasma sheet injection electrons with energies of tens to hundreds of keV. Combining ELFIN-THEMIS-DMSP observations and numerical simulations, this study provides strong evidence that kinetic Alfven waves may dominate over other wave modes or mechanisms in the driving of energetic electron precipitation from the substorm plasma sheet.
