Description

The central purpose of “Swarm+ investigation of energetic ion up/outflow” (“Swarm+ Outflow”) is to determine how Swarm spacecraft measurements of ionospheric plasmas and electromagnetic fields, together with measurements from other satellite missions and ground-based instruments, can be used to fill knowledge gaps related to the phenomenon of “energetic ion outflow,” or the intense loss of ionospheric-origin ions within and near the high-latitude auroral zone.

The project consists of five lines of inquiry:

  • Swarm-EISCAT conjunctions: Correlated electron temperatures, upward flow velocities, and small-scale B-field fluctuations
  • Swarm Echo: correlated upward flow velocities and field fluctuations
  • Swarm-Cluster conjunctions
  • Correlation between electron temperature and density, and ion upward velocity, with small-scale electromagnetic waves observed by Swarm
  • Swarm density measurements: hemispheric asymmetry in polar cap ionosphere plasma density around equinox?
