Space environment (natural and artificial). Operational estimation of the solar wind energy input into the Earth's magnetosphere by means of the ground-based magnetic polar cap (<i>PC</i>) indexWhat is ISO TR 23989 about? ISO TR 23989 provides guidelines for specifying the qualitative estimation of the solar wind energy input into the magnetosphere with the use of operative ground based information on the polar cap magnetic activity (PC index). ISO TR 23989 is designed for on line monitoring of the magnetosphere and forecasting the strength and extent of magnetic disturbances, as well as high latitude ionosphere data.
