Dataset
Spectral analysis of voltage data taken from the Canadian Riometer Array
Abstract
This dataset contains voltage data taken from the Canadian Riometer Array (CRA). The provided tables and datasets can be used to determine if the voltage time series of CRA riometers have characteristic spectral features. In addition, datasets are provided which have been collected from the Solar Wind Electron Proton Monitor (SWEPAM) and Magnetic Field Experiment (MAG) instruments aboard the Atmospheric Composition Explorer (ACE).

| Data Quality: |
The median filter of the riometer is unavoidable, coming with the instrument. This filter has heavy sidelobes, leading to a significant degree of smoothing of the population power spectrum of the riometer voltage process in the resulting estimates of spectral power. At points where there is significant variability over time scales around several minutes, the interpolation technique can struggle to provide a perfectly accurate reconstruction in places, although this has limited effects on the power-spectrum estimates included in the data files.
