The earth's atmosphere has been known for centuries to possess both electric and magnetic fields. Early scientific observations of geomagnetism and geoelectricity date back to at least the 1700's. More recently, electric and magnetic fields have been observed systematically in space where the terrestrial magnetic field extends to about 10 RE and meets the solar magnetic field. The increase in our knowledge of electric currents and fields in space over the past 3 decades has been truly explosive. In spite of the common thread of electromagnetism, there has been very little material published that covers both the neutral atmosphere and the ionosphere-magnetosphere. Hans Volland's contribution is to study the electrodynamics of these regions within a single monograph.
