Abstract

Abstract. A major explosion that released a significant amount of energy into the atmosphere occurred in Beirut on 4 August 2020. The energy released may have reached the upper atmosphere and generated some traveling ionospheric disturbances (TIDs), which can affect radio wave propagation. In this study, we used data from the Defense Meteorological Satellite Program (DMSP) and ground-based ionosondes in the Mediterranean region to investigate the ionospheric response to this historic explosion event. Our DMSP data analysis revealed a noticeable increase in the ionospheric electron density near the Beirut area following the explosion, accompanied by some wavelike disturbances. Some characteristic TID signatures were also identified in the shape of ionogram traces at several locations in the Mediterranean. This event occurred during a period of relatively quiet geomagnetic conditions, making the observed TIDs likely to have originated from the Beirut explosion, not from other sources such as auroral activities. These observational findings demonstrate that TIDs from the Beirut explosion were able to propagate over longer distances, beyond the immediate areas of Lebanon and Israel–Palestine, reaching the Mediterranean and eastern Europe.
国防气象卫星计划和地基电离层探测仪对与 2020 年贝鲁特爆炸有关的电离层扰动进行的观测
摘要2020 年 8 月 4 日在贝鲁特发生了一次大爆炸,向大气层释放了大量能量。释放的能量可能已经到达高层大气,并产生了一些行进电离层扰动(TID),这些扰动可能会影响无线电波的传播。在本研究中,我们利用国防气象卫星计划(DMSP)和地中海地区地基电离层探测仪的数据来研究电离层对这一历史性爆炸事件的响应。我们的 DMSP 数据分析显示,爆炸后贝鲁特地区附近的电离层电子密度明显增加,并伴有一些波状扰动。在地中海几个地点的电离图痕迹中还发现了一些特征性的 TID 信号。这一事件发生在地磁条件相对平静的时期,因此观测到的 TID 很可能来自贝鲁特爆炸,而不是极光活动等其他来源。这些观测结果表明,贝鲁特爆炸产生的热电离层能够传播到更远的地方,超越黎巴嫩和以色列-巴勒斯坦附近地区,到达地中海和东欧。

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.
