High Latitude Ionospheric Structures
John MacDougall
Dept. Electrical and Computer engineering, University of Western Ontario
London, Canada
High latitude ionospheric structures:-
• Polar Patches
• Polar cap auroras
• Poleward Moving Auroral Forms
• Sporadic-E
• Spread-F
• Troughs
• ?
Conclusions
• There are many different high latitude structures
• Most can easily be identified by their appearance on fixed frequency recordings
• It is not obvious that we have identified all the different types of structures
