Data and code for sample-based detection of high-latitude PALSAR-1 Faraday-rotation disturbances

Derived tables, figures, and MATLAB/Python processing scripts supporting a sample-based study of high-latitude ionospheric Faraday-rotation-angle disturbances in full-polarimetric ALOS PALSAR-1 data. The package includes scene-level local FRA disturbance metrics, event-level candidate rankings, PFISR/ASI/DASC/GNSS support summaries, manuscript figures, and processing scripts. Raw PALSAR-1, PFISR, optical, and GNSS data are not redistributed and should be obtained from their original archives.
