本文件为潜在用户提供了电离层密度和温度的全球分布规范，以及50？km至1500？km高度间隔内电子的总含量规范。它包括并解释了模型的等离子体非球面扩展的几个选项，包括在一天中的任何时间、一年中的任何一天以及各种太阳和磁活动条件下，纬度在80°S和80°N之间，经度在0°E和360°E之间的地理区域。 附件A简要介绍了电离层和等离子体非球面物理学。附件B概述了物理模型，因为它们对于理解和模拟产生电离层等离子体的物理过程很重要。

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 50？km to 1？500？km. It includes and explains several options for a plasmaspheric extension of the model, embracing the geographical area between latitudes of 80°S and 80°N and longitudes of 0°E to 360°E, 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 Annex？A. Annex？B provides an overview over physical models, because they are important for understanding and modelling the physical processes that produce the ionospheric plasma.
