2026-01-26 Daytime ionospheric density enhancement driven by poleward neutral wind shear associated with gravity waves during the November 2025 geomagnetic storm doi:10.57760/sciencedb.space.03485 en This dataset comprises ionospheric observations collected during the geomagnetic storm on 12 November 2025. It includes electron density, electron temperature, ion temperature, and plasma line-of-sight velocities measured by the 11 beams of the Sanya Incoherent Scatter Radar (SYISR). Additionally, plasma drift and neutral wind parameters derived from SYISR observations are provided. The dataset also contains Beidou geostationary Total Electron Content (TEC) data, obtained from the Beidou Ionospheric Monitoring Network (established by the University of Science and Technology of China) and the International GNSS Service (IGS) network and the simulation results from the Thermosphere-Ionosphere Electrodynamics Global Circulation Model (TIEGCM). daytime ionospheric positive storm; Beidou TEC; SYISR; poleward meridional wind shear Qi Jiang Jiuhou Lei PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
