A matched dataset of multisatellite TEC variability and observation opportunities at Hainan
Listed in ScienceDB
This dataset provides operational multisatellite GNSS total electron content (TEC) variability events observed at Danzhou, Hainan, during 2015–2020, together with one conditionally similar non-event for each event, common ±180-min sequences, and every valid five-minute detection opportunity.
Description
Simultaneous variability on several satellite–receiver paths is less dependent on any single path than a one-satellite anomaly.
The matched non-events and observation-opportunity denominator support event studies, observation-adjusted statistics and leakage-aware machine learning. The release contains 5,342 operational events, 5,342 matched non-events and 476,645 valid observation centres. Labels are reproducible operational candidates rather than confirmed physical mechanisms.
