Physics of the Upper Polar Atmosphere [electronic resource] /
Brekke, Asgeir.author.
This is the  only  extended textbook that covers in particular the physics of the upper polar atmosphere where the polar lights demonstrates the end product of a process taking place at extremely high latitudes between the solar wind and the upper polar atmosphere. A textboook that meets the modern requriement for reading in order to obtain a master of science or a Dr. of science degree in  upper polar atmosphere physics or the interaction between the soalr wind and the Earth's atmosphere.
