statistical modeling of saps location

What are saps?

• SAPS are westward directed flows observed in subauroral ionosphere.
• Traditionally, they were expected to occur during geomagnetic storms/disturbances.
• Sources:
  • Separation between ion and electron precipitation boundaries.
  • Electric fields in the sub-auroral region (Pedersen currents).
