This document provides guidance to potential users for the specification of the global distribution of ionosphere densities and temperatures, as well as the total content of electrons in the height interval from 50km to 1500km. It includes and explains several options for a plasmaspheric extension of the model, embracing the geographical area between latitudes of 80S and 80N and longitudes of 0E to 360E, for any time of day, any day of year, and various solar and magnetic activity conditions.
A brief introduction to ionospheric and plasmaspheric physics is given in AnnexA. AnnexB provides an overview over physical models, because they are important for understanding and modelling the physical processes that produce the ionospheric plasma.
