Ionosphere as a whole is
WebRegions with higher concentrations of ions and free electrons occur at several different altitudes and are known, as a group, as the ionosphere. There are three main regions of the ionosphere, called the D layer, the E layer, and the F layer. WebA common measure for the quiet time ionosphere are median values of the ionosphere during one solar rotation period (27 days). The deviation of the ionosphere from the quiet values (median) are considered as ionospheric perturbations. The service provides a map of Europe presenting the current level of ionospheric activity (perturbations of foF2).
