Abstract

Abstract. In this paper, we present the SafeSpace prototype for a safety warning system, dedicated to the electron radiation-belt-induced internal charging hazard aboard spacecraft. The space weather tool relies on a synergy of physical models associated in a chain that covers the whole Sun–interplanetary-space–Earth's inner magnetosphere medium. With the propagation of uncertainties along the modelling pipeline, the safety prototype provides a global nowcast and forecast (within a 4 d lead time) of the electron radiation belt dynamic as well as tailored indicators for space industry operators. They are meant to inform the users about the severity of the electron space environment via a three-coloured alarm system, which sorts the index intensity according to a representative historical distribution of in situ data. The system was tested during the challenging 2015 St Patrick's Day storm in order to assess its performance. It showed overall good nowcasting and forecasting capabilities due to its broad physics-driven pipeline.

基于SafeSpace建模的电子辐射带安全指标管道，专用于内部充电风险

摘要在本文中，我们提出了一个安全预警系统的SafeSpace原型，专门用于航天器上电子辐射带引起的内部充电危险。空间气象工具依赖于一系列物理模型的协同作用，这些模型覆盖了整个太阳-行星际-空间-地球的内部磁层介质。随着不确定性沿着建模管道的传播，安全原型提供了电子辐射带动态的全球临近预报和预测(在4天的提前期内)，以及为航天工业运营商量身定制的指标。它们旨在通过三色报警系统告知用户电子空间环境的严重程度，该系统根据现场数据的代表性历史分布对指数强度进行分类。该系统在2015年圣帕特里克节风暴期间进行了测试，以评估其性能。由于其广泛的物理驱动管道，它显示出整体良好的临近预报和预测能力。

期刊介绍： Annales Geophysicae (ANGEO) is a not-for-profit international multi- and inter-disciplinary scientific open-access journal in the field of solar–terrestrial and planetary sciences. ANGEO publishes original articles and short communications (letters) on research of the Sun–Earth system, including the science of space weather, solar–terrestrial plasma physics, the Earth''s ionosphere and atmosphere, the magnetosphere, and the study of planets and planetary systems, the interaction between the different spheres of a planet, and the interaction across the planetary system. Topics range from space weathering, planetary magnetic field, and planetary interior and surface dynamics to the formation and evolution of planetary systems.
