WebStudies of ionospheric currents tell us about interactions with space environment, including how energy is transferred between the magnetosphere and the ionosphere, and where it is dissipated. Since the main ionization source is solar EUV, every planet and moon with an atmosphere also possesses an ionosphere. More than 100 geomagnetic observatories around the world measure regularly the variations of the earth's magnetic field. The daily variations during selected days of quiet geomagnetic activity are used to determine a monthly mean. From the horizontal component ΔH of such data, one can derive a corresponding overhead equivalent electric sheet current system at dynamo layer heights of …

WebScintillation is caused by small-scale (tens of meters to tens of km) structure in the ionospheric electron density along the signal path and is the result of interference of refracted and/or diffracted (scattered) waves. Scintillation … WebA very weak current flows from the ionosphere to the ground. Conduction of electricity in the atmosphere is a little different from what happens in a wire. In a wire it is the motions of free electrons alone that carry current from one point to another. In the atmosphere charge carries of both polarites carry current. durand bourgoin
