TL;DR: In this paper, the maximum ionospheric electron density at F2 peak (NmF2) recorded an unusual large enhancement during the afternoon-sunset sector by the Chinese ionosondes over Wuhan (30.5°N, 114.4°E) and Xiamen (24.9°E), which are close to the earthquake epicenter.

TL;DR: In this article, the authors used the global ionospheric maps (GIMs) produced by JPL to investigate the longitudinal structure of the low-latitude ionosphere.

TL;DR: In this article, the authors investigated the propagation of large-scale traveling ionospheric disturbances (LSTIDs) during the super magnetic storm of 29 - 30 October 2003 and found that three LSTID events were observed in the range of 30 degrees N - 50 degrees N, 60 degrees W - 110 degrees W during this period.

TL;DR: In this article, more than two years of COSMIC electron density profiles at low solar activities are collected to study the evolution of the Weddell Sea Anomaly (WSA), which appears as an evening enhancement in electron density during local summer.

TL;DR: In this paper, the authors analyzed 11 years' (1998-2008) worth of the total electron content (TEC) data derived at the Jet Propulsion Laboratory (JPL) from Global Positioning System (GPS) observations to investigate the overall climatological features of the ionosphere in a new way.
