2026-08-21 Derived event-control data and analysis software for Spread-F and low-latitude GNSS TEC disturbances at Hainan (2015–2020) doi:10.57760/sciencedb.00zlz en This record contains author-generated derived data and versioned analysis software supporting a matched event-control study of 5,342 synchronized multisatellite GNSS total electron content disturbances at Hainan during 2015–2020. Contents include frozen event-control metadata, satellite-window summaries, ResNet50-derived Spread-F morphology labels linked within ±7.5 min, absolute 30–120 min amplitude and relative spectral pair tables, dependence-aware occurrence results, timing and viewing-geometry sensitivity outputs, 8,700 injection-recovery results, source data for six manuscript figures, and Python programs. The record does not redistribute 30 s TEC time series, original ionograms, image pixels, or source ionosonde parameters. Those observations remain available from the Chinese Meridian Project through the cited product DOIs and under its registration and use conditions. low-latitude ionosphere; GNSS total electron content; Spread-F Zheng Wang Hao Du PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
