精确地观测电离层的三维变化及其时间演化一直是空间天气界的一项挑战性任务。近几十年来，随着从多个地基和空间来源获得的电离层数据的迅速增加，在实施电离层成像方面取得了巨大进展。三维电离层成像可以得到目标区域的高度分辨电子密度和总电子含量（TEC）分布。它为更好地说明和了解电离层动态变化以及空间气象应用提供了一个基本工具，以支持政府和业界防备和减缓极端空间气象影响。为了在未来十年内更好地实现上述目标，本展望文件建议各机构继续投资，并通过社区开展联合研究，以支持推进三维电离层成像方法，使其具有更高的分辨率和精度、更好的误差协方差规格和不确定性量化、更好的电离层驱动因素估计、支持空间天气临近预报和预报，并持续努力扩大全球数据覆盖面。
Accurately imaging the 3-D ionospheric variation and its temporal evolution has always been a challenging task for the space weather community. Recent decades have witnessed tremendous steps forward in implementing ionospheric imaging, with the rapid growth of ionospheric data availability from multiple ground-based and space-borne sources. 3-D ionospheric imaging can yield altitude-resolved electron density and total electron content (TEC) distribution in the target region. It offers an essential tool for better specification and understanding of ionospheric dynamical variations, as well as for space weather applications to support government and industry preparedness and mitigation of extreme space weather impact. To better meet the above goals within the next decade, this perspective paper recommends continuous investment across agencies and joint studies through the community, in support of advancing 3-D ionospheric imaging approach with finer resolution and precision, better error covariance specification and uncertainty quantification, improved ionospheric driver estimation, support space weather nowcast and forecast, and sustained effort to increase global data coverage.
