Code and Data for “Citizen Night Sky Imagery Unravels Nonlinear Evolution of Ionospheric Bubbles”

This dataset contains the observational data, derived data products, and MATLAB analysis codes associated with the study “Citizen Night Sky Imagery Unravels Nonlinear Evolution of Ionospheric Bubbles”. The archive includes citizen-contributed and publicly shared night-sky imagery, night-sky meteor-livestream observations, OI 630.0-nm all-sky airglow images, GNSS observations, ionosonde data, Sanya Incoherent Scatter Radar (SYISR) plasma-drift measurements, and the corresponding analysis codes. It also includes a controlled synthetic multi-site three-dimensional tomography experiment for evaluating the feasibility of reconstructing EPB morphology from coordinated optical observations. The observational datasets and codes support the quantitative analysis, independent validation, and Extended Data figures presented in the study. Third-party night-sky imagery remains subject to the copyright and reuse conditions of the original photographers or sources. Detailed descriptions of the data, code, processing procedures, reproducibility information, and reuse conditions are provided in README.txt.
