  "x_descriptionLong": "Raw power from the Space Weather Adaptive Network (SWAN) Hyper-Spectral Riometer (HSR) at this site, recorded at 1-second cadence across multiple frequency bands. Riometers measure ionospheric opacity through the absorption of cosmic radio noise. The band central frequencies are provided by the band_central_frequency parameter (the time-varying bin centers of raw_power), since the band configuration can change over time; bands beyond what the site recorded on a given day are the fill value (NaN).
